First understand the ten heavenly stems: A, B, C, D, Wu, Ji, Geng, Xin, Ren, and Gui.

Here comes the key point: they correspond to the AD years ***4, ***5, ***6, ***7, ***8... and so on to ***3 years. That is to say, the years ending with AD 4, 5, 6, 7, 8...3 are respectively A*, B*, C*, Ding*, Wu*...Gui* year.
Be sure to remember clearly that the ten heavenly stems and the AD year are fixed and will not change! The change is twelve earthly branches !
The twelve earthly branches: Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai!
The key point is here: they are fixedly matched with the twelve zodiac animals, Rat, Chou Ox, Yin Tiger, Rabbit, Chen Dragon, Si Snake, Wei Sheep, Shen Monkey, Unitary Rooster, Xu Dog , and Hai Pig.

He said: There are only twelve in the whole of China, but 1.3 billion people have one!

In less than ten seconds, I told him: the twelve zodiac signs!
He was stunned and said how many talented people this fan had defeated! You guessed it in less than ten seconds! He was a little frustrated and asked me angrily: Have you seen this riddle before?
I said: First time listening!
