What does Jiang Yan mean when he calls Rong Shu "Gao Yanei" in the TV series "The Arrow is on the String"?

You must first know what Gao Yanei is before you can understand it in line with the plot. Gao Yanei was originally a follower of Gao Qiu in the market. After Gao Qiu became prosperous, he used all means to cling to Gao Zhi, and he did not hesitate to become Gao Qiu's son. It is enough to prove that Yanei is a 100% scoundrel who will do whatever it takes to achieve his own wealth.
