16 My nephew went to my uncle's house for 55 days in the summer vacation and lost my uncle's 60,000 wife's book. what do you think?

My uncle is a good uncle. It is said that my nephew is very close to my uncle. But 16' s nephew's parents are a little too taken for granted. 55 days is not a day and a half, so many people, how much does each family get? ? ? Human feelings or human feelings, the number must be clear, not vague. Because this is not a matter of one or two days, but the living expenses of 16 people for 55 days. As the parents of the children, you must pay the children's living expenses. ?
