How much is the deposit for 7 days hotel in Beijing?

The deposit is generally higher than your room rate. The five-day room rate will not be less than 750, so the total deposit will not be less than 800. I suggest you pay by credit card. You can pre-authorize the hotel first, and then complete the pre-authorization when you check out. You don't need to bring a lot of cash. (Pre-authorization means that the hotel freezes your amount first, and completing pre-authorization means completing payment. )
