I don't think so There is no such classification for CCB credit cards in integral mall. I usually exchange phone bills (6000 points for 10 yuan, 1 1000 points for 20 yuan, 28000 points for 50 yuan and 54000 points for 100 yuan), which is more practical. There are many kinds to choose from, and the landlord can also see if there is anything else he wants to exchange. His credit card points are permanent and will not be cleared regularly. You can also accumulate more points and change to a big one.
