There is a joke about Tsingtao beer and Laoshan beer. Have you heard of it?

A company is waiting to travel to Qingdao, and the tour guide introduces the scenery and specialties of Qingdao with great interest. Naturally, beer was introduced, saying that Qingdao not only has Tsingtao beer, but also Laoshan beer. The manager of the company came with his wife and a close friend. As soon as he got off the bus, he called the tour guide: "Look, I brought my wife and secretary. Ask me whether to drink Tsingtao beer or old beer at dinner later. Listen to me tonight and drink Tsingtao beer. " The guide had no choice but to agree.

At dinner, the tour guide asked, "Leader, do you want to drink Tsingtao beer or Laos beer today?" The leader said, "Try some Lao beer." The tour guide found out and gave his wife a single room at night. The leader's wife asked, "I came with my husband." How can I get a single room? " ? The leader came out in circles: "It is rare to come out to play cards with subordinates at night, so you can sleep alone." His wife thought so and didn't ask too much.

At dinner the next day, the tour guide asked, "Does the tour leader drink Tsingtao beer or Laos beer?" The leader said, "Let's have some old beer." He gave his wife a single room. On the third day, on the way to travel, my wife found that everyone in the car was very energetic, and only her husband and secretary were sleepy. She asked the others: Don't they all play cards together in the evening? Why are you in such a good mood? Others are at a loss to say that you have never played cards. His wife called the tour guide to ask. The tour guide can't hide it, so he has to confess. His wife was very angry and said, "What about tonight? I will take care of everything. "

At dinner in the evening, the tour guide asked again, "Leader, do you drink Tsingtao beer or old beer today?" The leader slept all day and knew nothing. He waved and said, "Let's drink old beer." His wife slapped him and pointed to the leader's nose and said, "If you dare to drink old beer again today, I will let everyone taste Tsingtao beer!"
