Ask a joke, "Do you want to trade?" What is the specific meaning?

While walking on the road, a person suddenly came out and asked with a warm and ambiguous expression, "Do you want a disc?", and then took out two CDs from his arms, "Man and beast are in love!"

I was very excited to buy it.

I went home and took a shower. I opened it excitedly and saw a woman flying on the screen: and then it was "The Legend of the New White Snake"

I knew this .

Sweat.

I shot it myself.
