Jokes about the Sichuan Army, grass children and cloth children. What's the point of the joke?

I lied to my wife in the afternoon that I had to work overtime in the evening, but actually I was going to play mahjong with my friends in a convenience store!

After getting off work, I went to the convenience store and touched it a few times before my wife came in. Fortunately, she saved some face for me, so I went back with her! < /p>

Then my dad came up and said, "I just saw this when I was buying cigarettes!"
