②, each person can answer no more than twice, and after two times, even if the answer is correct, it will be invalid.

③. It is forbidden to maliciously brush the building, otherwise it will be banned directly.

④, some questions not only need to give the correct answer, but also need to give the steps to solve the problem. Otherwise it is considered wrong. I will indicate the questions that require steps to solve them.

Reward: The winners of each issue will get a red envelope of 8.88 yuan for Xueba! ! ! ! 8.88 yuan! !

At the end of each session, the top three book lovers will receive mysterious rewards.

How to receive the award: On the second day of each question, I will explain in the official chapter who the award-winning book friends of the previous issue are. Then, the book friend entered the group and privately chatted with me to receive the red envelope.

The time limit for claiming the prize is one day. That is, 24 hours after I said in the chapter "xxx got the red envelope of Xueba in the previous issue". If no one picks it up after the time, I will send the red envelope as a bonus in the group.

Mmmm, finally, finally!
