Xinjiang produces the best and sweetest fruits in China because of the long daylight hours and the vast temperature differences between day and night. You can buy slices of melons at the night market and decide which one you like best.

Akbar Azmet's melons were cooled in icy water at the back of his tractor. For him the heat wave is a godsend because the hotter it is the more melons he sells. After years of practice he can slice every piece of melon into almost exactly the same size.

As people just cannot resist a slice of chilled watermelon in the hot summer night, the 45-year-old has to keep on slicing watermelons to satisfy his customers waiting in line. After a customer finishes the first piece, Azmet puts another slice into his or her hand and says: "Come on. You know you want another piece."

When you are in Hotan there are so many interesting things to watch out for, one of them being your weight.
