Full coverage: Chinese Mid-Autumn Festival

Wu Gang was a woodchopper. He always wanted to become an immortal, but he never tried his best to learn the necessary theurgy. The Jade Emperor got angry with him because of his attitude. In order to punish him, the Jade Emperor planted a huge cherry bay, which was 1665 meters (5460 ft) high, on the moon and ordered Wu Gang to chop it down, then Wu Gang could become an immortal.

This time, Wu Gang was very serious, but he could never finish his work. The cherry bay healed every time that Wu Gang chopped it. Wu Gang wouldn’t give up. He tried time and time again. On unclouded nights people can see some obvious shadows on the moon. They are made by the huge cherry bay.
