In the morning, I bought pork ribs and soybeans at the vegetable market, and then made soup with pork ribs and soybeans, and simmered for two hours.
Boil a pot of water again, put the pho in it and heat it up. After the rice noodles are cooked, pick them up, pour the pork ribs and soybean soup into the rice noodles, and then add the beef offal. A delicious beef offal soup is complete.
