sherry's notebook entry: The Mid-autumn Festival Since ancient times, China has had many fairy tales and legends about the moon. The most famous one is Chang Er Flying to the Moon. It is related to a traditional festival in China - the Mid-autumn Festival, which is coming up soon. It is the 15th day of the 8th lunar month. Usually we eat moon-cakes and many delicious Chinese dishes on that day. Do you like Chinese food? I believe that most of the foreigners like Chinese food. ^-^ But I don't know whether they like moon-cakes or not. Chinese people emphasize on reunion on Mid-autumn Festival, especially family reunion. So there is another name for Mid-autumn Festival, that is Family Reunion Festival. People often send round moon-cakes to their relatives or friends as gifts in expression of their best wishes of family reunion. At night, all of the family members sit together eating, drinking and chatting to celebrate the important day. Oh, there's one more thing. Don't forget to enjoy the beautiful full moon. Maybe you'll see Chang Er in the moon. :D

sherry's notebook entry: Sep 13, 2010 首先，让我感叹一下，中国真的是地大物博，人口众多。哪儿哪儿都是中国人，连网上都不放过，放眼望去五星红旗那个飘啊，哗哗的~~连外国朋友都说there are many people in this site from China。 其次，时差。想找个native speaker真的不容易，总是我们睡觉的时候人家工作，我们工作的时候人家却在睡觉，没有交集啊。 唉~~我抓狂！italki我挠你！◑﹏◐（貌似很久没发过牢骚了。。。）
