Shen Chen didn't seem to mind. Looking perfectly good-natured, he taught her which tiles to play and how to analyze the board.
"Brother Yu will definitely call that one, so don't discard it yet. Let's see if you can draw a tile to go with it."
"It's so late in the round and you're not ready to win yet. Don't risk discarding a tile no one else has played. We don't make losing bets."
"Baiyi is playing before you. If he discards something, don't call it unless you have to. It's better to just draw from the wall."
"Xie Er has been ready to win for a while. He's just waiting for that tile. Don't discard it."
Xu Su listened attentively to Mr. Shen's lecture the entire time. It was only at this last piece of advice that she couldn't help but retort, "How do you know that?"
