Today Yang Chen and I are playing a game of tennis.

OK, just a minute. To serve S-E-R-V-E is to put the tennis ball in play by throwing it up into the air and hitting it with a racquet.

OK. Good return, Yang Chen!

Love in tennis scoring means “Zero”.

Yes. Tennis scoring is very complicated, isn't it? To win a game a player must win four points and two more points than his opponent.

No.

It's just the tradition now, Yang Chen.
