Two companies went to the basement of Zhongguancun Silicon Valley in Beijing to recruit students. Take the motherboard as an example. Ask 1000 yuan until you learn it. Don't pack it with food. The route is also dedicated to you. Get off at 930 Langjiayuan, take the subway 1 to Xidan, get off at Fuxingmen, get off at Xizhimen, and take 808 across the street. It takes half an hour to get there ~
