Landlord, you can choose "Preferential Merchants" under "Credit Card Preference" of CCB Credit Card in official website, and then choose your region. You can see that local discount merchants all use credit cards to discount. I have a look, and there are the most cooperative catering businesses, but there is no way to search for the type of steak discount separately. At the same time, you can also click on "Special Price" to view the latest marketing activities of CCB. In Shanghai, we can use the Shanghai Hot Purchase Card to book the Steak, buy one and get one free.
