普通话 (Pǔtōnghuà), also known as Mandarin, is the official language of China and is widely spoken in Taiwan and Singapore. It is based on the Beijing dialect and serves as a lingua franca among the diverse linguistic groups in China. As the most spoken language in the world, 普通话 is essential for communication in education, government, and media. It uses simplified characters in writing, which were introduced to increase literacy rates. Learning 普通话 opens doors to understanding Chinese culture and society.
