Hello, everyone. I am Zhang Zhan(you can call me ZZ), from Chengdu, Sichuan Province, China, the hometown of pandas. For the past five years, I have been studying the relevant knowledge of urban planning. This blog is a good way to show my learning experience and life to everyone. At the same time, I am also interested in science and technology, and popular culture, and committed to finding their connection with urban design. This is the first time for me to using a platform like a blog, and I will try my best to do a good job every time. If you are interested in me or the content of the blog, you can also contact me.
