Can ancient people kiss?

Well said. China people will "kiss" from the beginning, but people call it "kissing the mouth" and "hooking the tongue". Moreover, because of feudalism, the ancients "gave and received without kissing", not to mention kissing in public. There are many descriptions of kissing in erotic novels of Ming and Qing Dynasties. For example, "first it became a' Lu' word, and later it became a' Zhong' word." Vividly shows the sexual process of a couple.

"Pro" and "Pro" are just changes in words, and there is no question of "yes" and "no".
