How to play hide and seek again?

1, first specify a range to determine who will find someone first, then that person will blindfold first, and within a specified time, such as 10 second, he will take off the blindfold and find someone else. This kind of land is generally flat and not easy to fall off.

2. On a large scale, people who hide can hide at will. If they hide well, the person looking for it can take off the blindfold and find it. You can see the place, and you won't fall. There are a lot of people hiding, any room or yard, even under the bed. It is not easy to find at present.
