What is the reason for the two-handled washing cup?
After the first hand is washed, it is clean and pure. The unwashed hand, however, is not. If the two hands touch after the first hand was washed, it is necessary to rewash the first one. We use a two-handled cup to make the process simpler, making it easier to avoid the hands touching each other.
