We still have to go there but yes it's China... unless you have a small cute dog in your house which makes a lot of noise!

Which is an interesting aspect in itself... another one. Could China be confused with Chihuahua in some way? You are the Mexican here so you tell me!
For the rest of your points I have the feeling it's not enough. I mean yes there's some interesting digging on your part, like the pirate flag used by cavalry, but I don't know if it leads where I'm imagining it should lead. Maybe we should search for the official explanation and put it under scrutiny. Don't know where to start though.
edit: btw, I almost missed the possible connection with the dogs you always show. If Chihuahua and China are the same then the canine head people (cynocephaly) coulod really be the Chinese as I've always thought. Possible European Latin speaking explorers confused the word China with Latin canis. This combined with the different bone structure of oriental faces compared to Europeans could lead to a misunderstanding, and Chinese faces became canine heads: Chihuahua-China-canis.
I don't really know why that place is called Chinao, but it is between Mexico City and San Miguel de Allende as far as I can see. It shouldn't be too far from Guanajuato or Jalisco, I also found the name on the Urbano Monte Map.

- In the red text with the letter B, it seems to me that it says that the people there are very hairless and beardless, just like the dog in this same region. The Xoloitzcuintle Xoloitzcuintle - Wikipedia is a very special type of dog in America.
Xolotl volunteered to perform such a feat, even though it would involve transforming himself into a dog; the Xoloitzcuintle. Xolotl was represented as a man with the head of a dog, representing the face of the nocturnal Venus accompanying the sun on its journey to the underworld. After sunset, the sun died and fought with his help to be reborn at dawn. Since then, this animal became the favorite of the gods. When the goal was achieved, it appeared before the dreadful Mictlantecuhtli, the lord of Death, and gave him the prized bone. Then, the Xoloitzcuintle returned to the world of the living and the gods were able to create the first man and the first woman. The Mexica tradition pointed out that it had to be completely black, because if it presented stains on its body, this meant that it had already served the soul of another deceased person. In addition, for the Mexica people, the Xoloitzcuintle had the ability to ward off and protect homes from evil spirits, but as everything for them was duality, it also represented an evil side since it was identified with illness and physical deformities.
- In the yellow area with the letter A it says that the people there eat human flesh and all kinds of animals.
- In letter C it says that in that place there were trees so big that ships were made from a single piece of wood.
By the way, I almost missed the possible connection with the dogs that you always show.
Something similar that I found could be this information:
The Chichimeca people in the north of Mexico, it is supposed that the Chichimecas arrived at Tollan (Tula) where a priest who was called Quetzalcoatl reigned like their god, the Chichimecas were commanded by a warrior named Xolotl, curiously he was called the same as the god of death and the underworld and brother of Quetzalcoatl.
The Nahuatl name Chīchīmēcah (plural, pronounced [tʃiːtʃiːˈmeːkaʔ]; singular Chīchīmēcatl) means "inhabitants of Chichiman," Chichiman meaning "area of milk." It is sometimes said to be related to chichi "dog"
Chichimeca - Wikipedia
Quetzalcoatl being the god of light, fertility, civilization, knowledge, the opposite of Xolotl. And everything points to the fact that there was a light-darkness duality before the arrival of the Mexica-Aztecs.
You can see how even Quetzalcoatl is represented with the face of a dog or very deformed and his skin is sometimes blue and bearded, both carrying a cross.
I had already shared a thread about Xolotl and Quetzalcoatl the brothers, the duality. This duality reminded me of blue Krishna and his dark skinned brother.

QUETZALCOATL - XOLOTL
I had the opportunity to read the book: Historia general de las cosas de Nueva España, they were direct impressions to the book and not PDF which I have not been able to find.
Florentine Codex - Wikipedia
Where it talked about Quetzalcoatl, it said that first came the Chichimecs who later called themselves Toltecs which meant "great builders", which in wiki says something like this:
Toltec culture or Toltec civilization - term of Nahuatl origin that has several meanings, the main ones being 'dweller(s) of Tollan/Tula' ('Place of tules') or 'artist, civilized, master' (their self-designation is unknown).
Toltec - Wikipedia
It is supposed that the Toltecs are the ones who gave civilization and knowledge to the warlike Aztecs, in fact it is said that the first Tlatoani or King, Emperor was Toltec, Acamapichtli.
In 1366 the Tepanec king Acolnahuacatl, in order to ensure the loyalty of the Mexica, accepts Acamapichtli (who was a Colhua prince of Coatlichan) on the throne of Tenochtitlan, thus initiating a new lineage for the latter city, which in turn will be proclaimed heir to the Toltec tradition.
Acamapichtli - Wikipedia
I still remember describing these Toltec-Chichimecs as being the size of two men, big runners, who did not speak Nahuatl well and were rather ladino.
During the conquest, the Chichimecas were supposed to still rule the north of Mexico and actually all the people of the north were called Chichimecas because they were barbarians.
José de Acosta
José de Acosta - Wikipedia , a Spanish Jesuit, anthropologist and naturalist who landed in America in 1571, for example, wrote in his Historia Natural de las Indias that the Chichimecas, the native peoples who occupied part of Mexico and reached as far as Potosí, were giants "who plucked the branches of the trees as we pluck lettuce".
CUAXÓLOTL, A CHICHIMECA DEITY?
Tonalámatl de Aubin (book of the tonalli or destinies of mystical character, that was property of the French collector Joseph Marius Alexis Aubin, Although they share their main assignment to Xólotl, deity of the pantheon of the Nahua, each one of them presents variants that show a great challenge of interpretation.
Xólotl, in his invocation of Cuaxólotl (head of Xólotl) with the Chichimecas and with the warlike activities.

About san cristobal there are also interesting things like this:
He is venerated by both the Catholic and Orthodox Churches as a martyr executed during the reign of Decius (Decius), emperor of Rome (who reigned from 249 to 251) or during the reign of the Roman emperor Maximinus Daya (Maximinus II Dacianus) (who reigned from 308 to 313).
Saint Christopher - Wikipedia
Catholics do not call him a dog's head but it is said that he had a hideous face.
His name means "bearer of Christ".
His famous legend, which is known especially in the West and could have been drawn from ancient Greek mythology (it would be the Christianization of the boat of Charon), I found some Etruscan murals where demons (blue) and angels appear, Caronte appears in a very peculiar way.
- The Tomb of the Blue Demons (Italian: Tomba dei Demoni Azzurri) is an Etruscan tomb in the Necropolis of Monterozzi near Tarquinia, Italy. It was discovered in 1985. The tomb is named after the blue and black-skinned demons that appear in a scene of the underworld.
- Charon, the Greek ferryman of the dead.
According to the legendary account of his life, Christopher was initially called Reprobus.
He was a Canaanite of 5 cubits in height (about 2.30 meters) and a fearsome face. After serving in the kingdom of Canaan, it occurred to him to go serve "the greatest king that ever lived." He went to serve the king who had the reputation of being the greatest but one day he saw that this king was sanctifying himself at the mention of the devil, But when he saw that his new master was turning away from a cross on the road he realized that he was afraid of Christ. A hermit then suggested to him that, because of his great size and strength, he could help Christ by helping people cross a dangerous river where people used to perish in the attempt. The hermit promised him that such service would please Christ.
St. Christopher is a very popular saint, especially for athletes, sailors and travelers (Christopher Columbus).
St. Christopher is the patron saint of many cities and towns around the world, including:
America and the Caribbean:
San Cristobal de las Casas (Mexico).
San Cristóbal de Alvarado (present-day Alvarado, Veracruz, Mexico).
San Cristóbal de Tlacotalpan (present-day Tlacotalpan, Veracruz, Mexico).
Locality of San Cristóbal (Bogotá, Colombia).
San Cristobal (Dominican Republic).
San Cristobal (Venezuela).
City of Jayaque, La Libertad (El Salvador).
District of Chepo (Panama).
St. Kitts Island (St. Kitts and Nevis).

Canaan (according to Catholic tradition).
Marmarica (according to the tradition of the Orthodox Church)
In the Gospel of St. Matthew (15:21-28) we see how Jesus worked a marvelous miracle for a Canaanite woman who insisted that he help her. In this story, we are presented with the story of a Canaanite woman, a Gentile and a foreigner, and for this reason she is despised and rejected by the Jews. But this does not bother Jesus, rather he attends to her, but only after a series of constant pleas. Jesus ends up comparing her to a little dog, but did Jesus insult the Canaanite woman by comparing her to a little pet?
¿Jesús insultó a la Mujer Cananea al compararla con un perrito?
a pagan Canaanite woman cried out to him in Jewish terms, "Have mercy on me, O Lord, son of David! My daughter has a very bad demon."
"My hour has not yet come." But the woman has great faith. She called Jesus "Lord" three times. It is a faith that is not only manifested in words but in action: "She came to prostrate herself before Jesus". Jesus resists: he does not want to be accused by the Jews of privileging the pagans, and he tells her: "It is not right to take the children's bread and throw it to the little dogs".
HB:
All these things I present to you about Blemios, Cinocephalos, could be the way people referred to the Cananites for being Can (dog) although Kan in Maya is Snake. Above all, this medieval costumes very well documented by Greek and Roman historians, did they exist or not? what do you say? I only share with you this interesting data and similarities without doubt, you see Piri Reis putting Blemios and Cinocephalos in the Amazon. Maybe in the medieval era they did as Isabel de Toledo says, the American continent was more than known but at the same time it was a well kept secret among the elite, that's why they said that the gold was brought from Africa, Africa was America, more precisely from the gold mines of Castilla in Colombia.
