Palo Alto, south of San Francisco Bay District, Stanford University, is a must-see place for San Francisco and the group. It is adjacent to Silicon Valley, surrounded by high-end villas, mostly people living in Silicon Valley, and the prices are high. At daybreak, the university has imposed strict restrictions on the time and route of group tourists due to the large number of tourists. Great golf greens, exquisite buildings, the world's top schools are not the same. What's more unexpected is that the kind of Chinese who publicize what kind of merit are looking at our tourists. First they get close to each other, then they begin to expose themselves. Every day they get up early to do this propaganda work and they really admire their perseverance.
