Time service is relatively easy, and working in the center is not so stressful. Because there is a team with a boss, not a person working. When you go to the household, you have more money, but you have to do more odd jobs, the time is irregular, and then there is a monthly meal. The family has to do all the cooking and do more housework. You should also know how to get along with others. If you get along well, you will be happier and life will be easier. On the other hand, if I meet a bad host, I'm not sure whether I can do it, so if I do, I'll choose to come again if I have to.
