Question

why would the relatives not com to harvest

Answer 1

I think because they have little shy in that work

Answer 2

It is very normal that no relative should be allowed to do any work.

But in some cases, it is necessary to get help from relatives.

In the same way, the relatives also need to be used for harvesting.

It is not possible for one person to harvest crops.

But relatives often hesitate to do this work. So I think it is not bad to use a relative in crop production.
