My troubles with making cents of Chinese currency

In my home country of the United States, I swipe for the things that I buy. Debit and credit cards are standard in the US, and before coming here, I was a bonafide member of the cashless society.

So here I am in Beijing, trying to get used to a thick wallet of cash, instead of a thin wallet with a couple of plastic cards.

My wallet is not set up for cash. Back home, I bought a nice leather wallet that only has slots for credit cards, and no place for paper money, and certainly no compartment for coins.
