As for the heroine Yang Shu, a good Chinese young man who learned amazing kung fu from his grandfather and his grandfather's friends. After his grandfather passed away, he finally couldn't stand the beating and scolding of his parents and collapsed. Helen Yang (Yang Shu) went to the United States to study. However, Yang Shu, who has well-developed limbs and a slightly flexible mind, has a poor memory and does not know how to work hard, so his grades and knowledge have never been acquired.
Due to an FBI arrest operation, Yang Shu got to know the people of the BAU and has been helping them intentionally or unintentionally ever since. Eventually, he fell in love with his supervisor Hotch.
Ps: Although Yang Shu has a slightly smart mind, he can be called an idiot when it comes to emotions. He has no experience at all and is not very enlightened. This makes Hotch extremely upset.

Ppps: hotch is 30 years old, poplar is 26 years old, reid is 26 years old,
