How did Niang prevent the children from rebelling against her?

. The brothers are given identical, loose fitting Chinese smocks while the sisters are given plain qipaos. They’re outraged by the “blatant inequality” (43) between them and Niang’s children, who received stylish western outfits for the New Years, and start to talk about how unfair life is. The youngest siblings have the most modern clothes, trendiest hairstyles, and unlimited access to the kitchen. They are allowed to buy anything they desire. The older siblings also complain about Niang’s spies, particularly Miss Chien, the younger children’s tutor. Eventually, the children attempt to get organized and revolt against Niang, by sending a letter to Father about how unequal their treatment is. Niang catches wind of this plot, and though she does nothing initially, she invites Big Sister to the second floor and converts her into a spy. The siblings cannot remain organized without the help of Big Sister and their attempts to change the situation cease.
