The main purpose of the Tiananmen Lantern Festival in China is to celebrate the Lantern Festival, which marks the end of Chinese New Year celebrations. During this festival, brightly lit lanterns, often featuring intricate designs and riddles, are displayed and admired. Families come together to appreciate the beauty of the lanterns, compete in riddle-solving, and indulge in traditional foods like tangyuan, glutinous rice balls symbolizing reunion. The event fosters community bonding and cultural connection, making it an integral part of the Lunar New Year traditions.
