Did China kiss in ancient times (mainly before Sui and Tang Dynasties)?

A university professor told his students: "in ancient times,' Lu' meant kissing, which was very vivid;" One of the students asked, "If' Lu' means kissing, how does' Pin' explain three people kissing together?"

The professor was about to get angry when another student stood up and said, "I think the word' product' is easy to explain." What about the' device'? " What are four people and a dog? "The whole class laughed, and the professor closed the book with a bang and left.

This is a joke to make you happy.

But what the professor said is really right. In ancient times, "Lu" meant kissing.

Think about it. There was a Lu. It was early.

In ancient times, kissing could not be spread abroad, so there was no official record. But the so-called food color, sex is also. The ancients, especially those in the pre-Qin period, were far more open than you and I thought.
