Joke bottom line

Don't challenge my bottom line, or I will revise my bottom line again. Degang Guo said it. "Don't challenge my bottom line, or I will revise my bottom line again." Degang Guo's speech in Weibo on September 28th, 20 14 seems to be a joke, but it is not absurd. There are many such phenomena in reality, because we have to weigh the pros and cons, and after considering all aspects, we may have to give up the bottom line and principles we have always adhered to. As Chen Danqing said, China people have no principles, only survival is the most important thing, and what is useful will be used.
