The holiday of Christmas is known by several different names in China. It is often referred to as "Jesus' Birthday" or "Christ's Birthday" in Chinese. In Hong Kong, it is also known as "Tung Sin" or "Tung Shin." The holiday is celebrated on December 25th, and many Chinese families put up Christmas trees, exchange gifts, and enjoy a special dinner together. However, the holiday is not as widely celebrated in China as it is in other parts of the world.
