What do you mean by burning pig's trotters?

1 This is what Wei Yingluo, the heroine of the TV series The Story of Yan Xi Palace, said.

Once she saw other ladies-in-waiting trying to attract the attention of Fu Cha Fu Heng, the bodyguard, and told them that men are unreliable and they are all big pig's feet, which means that men have no good things and are all liars.

Nowadays, most of the network meanings are commonly used expressions to express boys' change of heart and trustworthiness, and can also be used to spit out boys and steel straight men who don't understand amorous feelings.
