got married to the kind and beautiful Chang'e.An immortal神仙 gave Hou Yi a kind of medicine that could make him live forever,but he didn't want to leave Chang'e,so he let her keep the medicine.On the fifteenth of August,Feng Meng,one of Hou Yi's students,wanted to take the medicine away when Hou Yi went out.Chang'e didn't want to give it to him,so she had to take the medicine herself and flew up into the sky.Since she loved her husband very much and hoped to live nearby,she chose to stay on the moon.When Hou Yi came back and learned about what had happened,he was very sad.He put the fruit and cakes that Chang'e liked in the yard to show her his love.People soon learned about this,and began to copy Hou Yi's activities.From then on,the custom of enjoying the full moon during the Mid-Autumn

They would like to invite James to have a try.James was excited, “Many people think I look like Patrick Steward.” However, as he was going to leave China in 3 days, he wanted to try out after dinner. The man agreed.At 9:00 pm, when James asked for the bill so that he could go with the film-makers, the manager of Beijing Restaurant said sorry to him with a smile, “It’s April Fool’s Day joke! Your meal is free. Thank you.”James completely forgot about it but when he found that he was fooled, he didn’t leave at once. The waitress asked him if he needed some help.
