What are the Japanese zodiac signs of China?

Rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and wild boars.

The year of the ocean in China is called the year of the pig, while the year of the wild boar in Japan. Why? It turns out that the Japanese chronology of "heavenly stems and earthly branches" was introduced through China.

It is said that heavenly stems and earthly branches in China originated from Shang Yin more than 3,700 years ago, when the "tapir" was a wild boar. Later, wild boar was gradually domesticated as domestic animals in China, and jackals refer to pigs.

When heavenly stems and earthly branches was introduced to Japan, wild boar had not been domesticated in Japanese society, so for the Japanese at that time, wild boar was much more common than domestic pigs, so the year of the ocean was naturally called the year of wild boar.
