Dear Tim, Thanks for your letter. I am very glad to hear that you are fine. I am fine, too. It’s really interesting to know about vacations of America students. You are right. We have fewer vacations than American students. Each year, we just have about four vacations. We have a day off for Independent Day on September 2nd, two days off on April 30th and May Day. Our most important vacations is Tet. Tet holiday often lasts for nine or ten days. Our longest vacation is summer vacation. It lasts for almost three months. We usually spend time with our families.
