In the fourth part of Cold and Warm Rooms, Mrs. Dorje is an important role. She is the eldest daughter-in-law of Okakura's family and the head of the shop. She is a very capable woman, managing the affairs of the shop and the family, and trying to maintain the dignity and order of the Okakura family.

Mrs. Dorje's identity is quite complicated. She is not only the person in charge of the shop, but also the mother and mother-in-law of several children. She has been trying to balance the relationship between family and career, while dealing with contradictions and disputes with other family members.

Finally, Mrs. Dorje finally got a relatively happy ending. Although she experienced many difficulties and setbacks, she finally got the understanding and support of her family, and her efforts were rewarded. Specifically, she successfully maintained the operation of the store, reconciled the contradiction with other family members, and got the birth of her grandson and the growth of her daughter.

Generally speaking, Mrs. Dorje plays a very important role in the fourth part of Cold and Warm Rooms, and her efforts and dedication run through the whole plot. Although her ending is not completely perfect, it is also a satisfactory result.
