In the summer of 2019 I was able to spend four weeks in China. One week during The 37th Annual International Symposium on Lattice Field Theory (just "Lattice 2019" by the people in the field) in Wǔhàn (武汉市) and three weeks during a summer school "Frontiers in Lattice QCD" in Běijīng (北京市).
This is the first of a series of articles about my trip. You can find the whole Series via the China tag. The following map shows the cities that I've visited in China to give you a rough impression.
