Hehehe, you said that Zhihu is good at his major and knowledgeable, so this is also his shortcoming. I would like to ask "how to get to Hebei Grand Theatre?" I want to ask, "Is the name Koryo Cloud nice?" I want to ask, "Where are the XXOO resources?" I want to ask "Tell me about those who love high school" ... Can Zhihu give the answers to these questions? ! This is called grounding gas, not low-level. Give you a seed called low level? Show you a way called low level? Teach you a little common sense of life, called low? Hey ... Are you sure Zhihu didn't send it for irrigation? Baidu knows that there are plenty of clothes and milk and can tell you the meaning of life. Next, you can complain that you were forced to thunder. Don't think Zhihu is a great god once every two days.
