Mao arrives at Guangzhou and goes to the Yang Spring Restraunt. At first he is ignored by the master chef of the restraunt, Choyu. Mao shows him the letter of recommendation from General Lee to which Choyu becomes a bit suprised but just chucks the letter away and tells Mao to cook bakchoy (white chinese cabbage) for the chefs to eat for lunch. Mao cooks the bakchoy but the dish is turned down by all the other chefs. Later Choyu tells him that Guangzhou's water contains a lot of dirt so when Mao cooked the bakchoy all the dirt flavour went into it. Mao, being the talented cook he is immediately goes to work finding a way to get rid of the dirt taste. After just one day, Mao works out how to get rid of the dirt taste and begs Choyu to allow him to prove his skills. Mao cooks the bakchoy again, this time using an oil which prevents the cabbage from absorbing the dirt taste. Mao is congratualted by all the chefs for his smart thinking and is accepted Choyu promotes him to'fourth grade chef' for his achievement. Of course, this makes the other resident cooking master boy, Sanche, a little jealous.
