How much is the standard for a wedding banquet at the Changchun Red Cross Society?

You'd better call and ask. There are three halls, with minimum reservations of 40, 50 and 60 tables. Wedding banquets in these three halls have different prices, starting from 1,400, it seems. But the price will increase on popular days. There is a small hall that can accommodate ten tables and eight wedding banquets. I think the minimum order is 600 or 700. The venue fee you mentioned should be the price of their own wedding ceremony, which seems to be the price of those halls.
