Rice

Back in China in the 1950s, rice was a part of the economy. It was used to buy, to trade, and to sell. In the book Double Luck, Chi Fa's sister-in-law sold Chi Fa to a communist family for rice to buy a ticket to Hong Kong. Later on, Chi Fa's sister saved enough rice to buy Chi Fa a barge ticket to Hong Kong. She didn't want to buy the ticket with her husband's money because back them, their crops were getting taken over by communists. Rice is still a big deal
