Clara: Guess what? I'm going to Chiang Mai in two weeks.
Ben: Wow, sounds like fun! But I believe that April is the hottest month of the year there.
Clara: Yes, that's true. But there's a water festival there from April 13th to 15th.
Ben: I wonder if it's similar to the Water Festival of the Dai people in Yunnan Province.
Clara: Yes, I think so. This is the time of the Thai New Year. People go on the streets to throw water at each other.
Ben: Cool! But why do they do that?
Clara: Because the new year is a time for cleaning and washing away bad things. Then you'll have good luck in the new year.
