Dear Jack，
It's really a pleasure to hear from you．As everyone knew，great importance is attached to birthdays and their celebrations．
Chinese students celebrate their birthdays with different ways．But the most commonly way is to have fun drinking，singing and dancing．Just on one's birthday，one usually receives nice gifts and good wishes being presented by friends and parents．Sometimes，parents will prepare a special birthday party for their child．
Surely celebration is one of the most important activities in one's life，and even meaningful things than that can be carrying out．For example，you can buy some flowers or cook an usual meal for our parents on that very day．It is through these deeds，I believe，which we express thanks to our parents in return for their love．
