Chongqing to Shenzen and Shangai and Hongkong fast train and good food and senary train is ICE which germany borrows
Lucky for you, China is already in Train Simulator 22, with a few routes here and there. Also, the "ICE which Germany borrows" I take it you refer to this: In which case, Germany does not borrow this from China, it's near enough the other way round, with the Chinese one being based on the German design.
As I said above, China is already in this game. The only DTG game it's not in is TSW2. On your preferred store you'll find numerous Chinese routes - from the Shanghai Maglev to Conventional Railways.
