Here's my strategy of 8 cities :
1.Luoyang, on the plain hill, initial city. - Very strong city with Regulated Trade and Grand Canal, which should be built ASAP.
2.Beijing, 1W of fish, 1000BC. - For building troops. 2W of the fish is OK as well if you want the incense.
3.Wuhan, 1S of deer, 800BC. - For acquiring tea and dye. With only 3 cities your maintainance won't be high, so settle them ASAP.
4.Guiyang, between the two mountains, 400BC. - For acquiring gold and building troops. This city is productive but lack food. Dujiangyan is built here.
5.Haojing, west of pearl river delta, 200BC. - For hiring specialists. Rich food but less productive.
6.Hangzhou, 1NE of stone, 200BC. - For hiring specialists. Rich food but less productive.
7.Qingdao, 2E of Luoyang silk, 0AD. - Can support your core population if you grab Korea's fish.
8.Shenyang, 1N of wheat, 0AD. - Another way to expand into this area is to capture Barbarian Simiyan Hoton. Both are OK.
Your ideas may be different from mine - That's OK. There have been many different ideas of the 8 cities, all having their reasons and being suitable for their UHV strategy. But the general idea is that you should settle one more city if there're enough workers to improve these plots.
