In some public places, such as libraries, Internet cafes and railway stations, some deaf people will ask you for donations. Are they liars? I have donated many times.
The child is too young to be a liar. Undoubtedly, I have friends who are teachers in such schools. They never let students do these things. A person will misunderstand them. After all, they are deaf and dumb and unsafe. Their small handicrafts are sold in cooperation with some merchants or government departments.
