Excuse me, do you have a traffic card similar to Octopus, which is mainly used to take the bus and subway to Beijing? Where can I buy it?

Bus card outlets are not particularly easy for tourists to find. Let's go to the subway station to buy it. But there are several exits in the subway station, and only one is for sale. Find the subway station and ask the staff which entrance it is.

This is a prepaid card with a deposit in 20 yuan. There is no discount on the subway, and most buses can get a 60% discount. The only trouble is that there are few places to return the card. It is inconvenient for strangers to travel, and they have to find a place to return their cards. If you don't return the card, the money saved in these three to five days is not enough for the deposit.

See if there are many opportunities for you to come for a few days and then take a bus. My suggestion is to take the subway instead of the bus when going out in Beijing, and then don't apply for a card to save trouble.
