I will be travelling to China next week for work. Obviously, I will have some time to travel too.

I will be visitng Beijing, Tianjin and Hangzhou for work. Friday, the last working day of the week, I will be in Hangzhou.

My question is should I visit Shanghai cutting short my trip of Hangzhou(go to Shanghai on Saturday) or cut of Shanghai from my travel?

P.S : if I don't visit Shanghai at all, I will have 2 days (give or take half day) to travel Hangzhou.

My flight back is on the Sunday.
