In the world of plants, bamboo, together with plum blossom, orchids and chrysanthemum are called the Four Gentlemen or the four Noble Ones as they are believed to have something in common with human virtues. People believe that its deep root denotes resoluteness, its tall, straight stem represents honorability, its hollow interior modesty and its clean and spartan exterior exemplifies chastity.
Due to its characteristics, it has been highly favored by Chinese, especially the scholars. It can be commonly found in Chinese paintings and literary works.
When bamboo was placed in a fire it would create a loud crackling sound which was similar to firecrackers, therefore, in ancient times, it was always used to frighten away evil spirits, such as the mythical beast Nian.
