Tsai Chin Chung is one of Taiwan’s most famous cartoonists, and his cartoons are enjoyed by people in many different countries in Asia. His books of cartoons have now become best sellers in Singapore, Malaysia, and even Japan.

As soon as he could hold a pencil, Tsai Chin Chung lived only for drawing. Every day he practised drawing people and things around him and from his favorite stories.

When he was only 15 years old, he left home to work for a publisher in Taipei. He worked hard to draw pictures for books. Two years later, he left his job and started to work on drawing cartoon series, which he liked better. He made up his mind to succeed as a cartoonist.

Now Tsai Chin Chung has achieved something unusual for a modern cartoonist. He has become extremely successful at changing Chinese literature (文学) and philosophy (哲学) into humorous comic stories. In this way, he has made the Chinese classics (古典文学) known to thousands of people.

Because of his great achievement, several years ago Tsai Chin Chung was given a prize as one of the 10 Outstanding Young People of Taiwan. Since then, he has won many prizes, and his cartoons have become popular throughout Asia, America and Europe. So far, he has published more than 20 comic books. Ten of these are about ancient Chinese philosophers based on Chinese historical and literary classics.  

Many of Tsai Chin Chung’s books of cartoons and comics have now been published in English in countries like Singapore. His books have also been translated into several other languages, including Japanese, Korean and Thai. Even publishers in France and Indonesia have recently signed agreements for permission to publish his cartoon series.
