章 1160: Gao Yang's interrogation!

There were rules to follow before playing mahjong. Xu Yi was going to tell Xia Ning about it, but he thought it would be better for the couple to discuss it, so the most important task fell on Qiao Yu.

Qiao Yu took out a pen and a piece of paper from somewhere and explained the numbers and the basic rules of the game.

Finally, he directly listed out a few formulas on how to win the game.

Xia Ning looked at the formula, then at the cards on the table, which were automatically added to the formula.

Afraid that Xia Ning didn't understand, Qiao Yu picked a few Mahjong pieces and gave her a few examples.

Gao Wanhua and the others were dumbfounded as they watched the couple ask and answer questions. Were they playing mahjong or studying mathematical formulas?

About ten minutes later, the card game began.
