Most of the pianos used in kindergartens are teaching pianos (vertical), such as Zhujiang 1 18M or Xinghai 1 18D, which are not much different from the domestic pianos, but the timbre is bright and the piano height is short. Other structures and feel are the same, and there are family conditions that can almost afford to teach piano practice. At present, the piano in China has developed rapidly, with dozens of piano factories, the piano output ranks first in the world, and the domestic piano has also been greatly improved. Most common pianos used at home are 120~ 125. Piano timbre has also made great progress. The cooperation and joint venture with foreign countries have improved the piano manufacturing technology. There are many patterns, and wealthy families are equipped with grand piano.
