Let's talk about the video of my sister paying rent first.

Although they are brothers and sisters, they all have their own jobs, and no one has the obligation to support them. Therefore, it is reasonable to calculate the living expenses for about one month in advance, and the brothers with better income can earn more in proportion. The two brothers and sisters can discuss it. There is no need to calculate the basic living expenses too clearly. The key is not to have the concept of who is going to pay for whom. As adults, everyone is independent, but the family relationship is not clear. Moreover, it is also important to cultivate economic independence and sense of responsibility. So my brother lives in my sister's house, and the rent should be collected by my sister.
