Three Blessings?

Every piece of furniture was more than enough for everyone. 

Only Xue Yan, Jiang Yue, and Xue Sifu's rooms each had an additional desk, and a large bookshelf by the wall.

Originally, the family planned to only get a desk and bookshelf for Xue Yan and Jiang Yue because only Xue Yan and Jiang Yue were literate. However, Xue Sifu said that if he wanted to expand his business in the future, he would need to learn how to write and read. Now, he was at a disadvantage because he could not read. Therefore, he also got a desk and bookshelf to study in the future. However, Dafu was afraid that the others in the house would also want to read, so he still made a study room in the house.

There were only two guest rooms, and the furniture inside was much simpler.
