It has been 10 years since it was released in Zhihu. We can learn a lot from Zhihu. If we have some puzzles in our daily life, we can also write these questions on Zhihu, and someone will naturally answer them. However, in this 10 year, we will always find some wonderful problems on the Zhihu. Today, let's take stock of the wonderful problems I have seen in Zhihu.

1. One of the wonderful questions that impressed me the most on Zhihu was that an author was asking, Is it illegal to sexually assault giant pandas? And said that he has no resistance to giant pandas. I feel that I have fallen in love with the giant panda deeply. But don't be fooled by MengMeng's appearance. You should know that pandas eat bamboo, but this bamboo is hard and the panda has a strong bite. If you really sexually assaulted the panda, you might be dead. In addition, pandas are protected animals of the country, and sexual assault on pandas is definitely illegal.

2. Another topic is to ask questions in Zhihu. In the process of steaming crabs, he felt that all the live crabs were ripe. This process is cruel, and he feels that he can't eat it in an instant. However, I just want to say, if I can't eat, please give me the crab.

3. Another question is about kangaroos. As we all know, kangaroos don't walk on two legs, but usually jump. But the question raised by this topic is that kangaroos generally jump when they walk, so will such behavior hurt their knees? After all, people's actions will hurt their knees, but I want to say that kangaroos are not people, but are caused by the theory of biological evolution. Kangaroos have to face the way of jumping, and we walk upright every day, which will hurt our knees if we walk for a long time.
