This time, I really had to talk about purified water. Feng Xiao could tell everyone from personal experience that purified water really could not wash soap off properly.
Some friends said that the harder the water, the better it was at getting rid of soap suds. That was absolutely true. Anyone who did laundry often knew that the harder the water, the more soap it used. These were simply two sides of the same coin.
