Founded in 1988, Jiangsu Chimei Musical Instrument Co., Ltd. has a variety of products covering harmonica, cucurbit, recorder and other musical instruments. Its melodica and recorder account for more than 90% of China's domestic and foreign trade market share. Chi Mei occupies the mainland market with its low price, which is aimed at music classes for teenagers. However, Chimei's performance in various musical indicators is unsatisfactory, the bass is hoarse, and the treble cannot go up. Overall, CHIMEI is a toy that is more suitable for children's musical enlightenment, and it is not recommended for friends who have high requirements for performance.
