    China is a country with many colorful days and festivals. The Dragon Head Raising Day (Longtaitou) is one of them. This special day is on the second day of the second month in the Chinese lunar calendar. It stands for the start of spring and farming.

    The dragon is important for Chinese people. We Chinese people call ourselves the" descendants(传人)of the dragon" . Therefore, people celebrate the Dragon Head Raising Day with many customs.

    On the day in ancient times, people put ashes in the kitchen. This was to" lead the dragon into the house". People believed that with the help of the dragon, they could have a good harvest(收成)in autumn.

    Also, people cat special foods that day. The foods are usually named after dragons. For example, people eat" dragon whisker(细须)"noodles and dumplings called "dragon teeth " .

    Today, many customs have faded away(消退). But one that has remained is the cutting of hair. It is said that a haircut during the first lunar month may bring bad luck to the uncles of the family-mainly mother's brothers. So many people have their hair cut on the Dragon Head Raising Day.
