P I'm playing Kung fu video games.
Y Kung fu电动游戏多没劲，Let me teach you some real Kung fu moves.
P: You know Yang Chen, I think Kung fu may be the only sport where you have the upper hand on me.
P: I'm not scared. I have lots of experience playing Kung fu video games by myself at home.
Y: Only losers play Kung fu video games by themselves at home.
P: You really don't pull your punches, do you, Yang Chen?
Y: What do you mean 'pull my punches'?
P: When you pull your punches, that means you hit someone only lightly so you really don't actually hurt them.
Y: You mean手下留情。Don't worry.
P: That's what I was afraid of. You know, you can use "pull your punches" when you're talking about criticizing people too. For example, I didn't pull any punches when I criticized my boss's new plan to reduce everyone's salary.
Y: Oh 你敢批评老板? 而且还didn't pull any punches 。勇气可嘉。But I'm worried about you. Do you still have a job?
P: Nope. He got mad and fired me. That's why I'm trying to become a professional Kung fu master for my new career.
Y: Well, 学点儿功夫也好。 教训一下你的老板。Maybe he'll hire you back.
P: That's the plan.
Y: That's a good plan.
P: Now let me show you some of the Kung fu moves I've learned from watching Bruce Lee movies.
Y: That's the worst Kung fu I've ever seen.
P: I can see you're not pulling your punches when you make fun of me!
Y: Don't feel bad. At least you can scream even better than Bruce Lee.
