Planning a two month trip to China. Which cities would you cross off this list?

Hey y'all. Going to be traveling through China for a total of 62 days starting December 26th after spending Christmas in Hong Kong. This is my current rough outline of cities, along with the amount of potential days in each one. Anything y'all would cross off this list or certain cities you would extend stays in? (I also have a preference towards museums and art scenes in major cities. Don't mind hikes either.)

Shenzhen: 4 Days

Guangzhou: 4 Days

Chongqing: 9 Days

Chengdu: 4 Days

Xi'an: 4 Days

Wuhan: 7 Days

Beijing: 9 Days (Would be here for Lunar New Year)

Tianjin: 4 Days

Jinan: 4 Days

Nanjing: 4 Days

Hangzhou: 4 Days

Shanghai: 3 Days (Have been to Shanghai before. Love it, but am comfortable skipping it. Flights back to the states are just cheaper from here.)

Thanks for the help! I'd honestly be grateful for any advice!
