for a time zone.
In this case, what's wrong with calling the tz zone Asia/China and being
done with it?

suitable to use the population rule. Because the most populous
location in China is Chongqing, which is belong to Sichuan province,
the most populous province of China. But Chongqing is far less
developed than Shanghai and Beijing, so it's far less popular than
Beijing and Shanghai.

location, Beijing, the capital of China to identify our unique
