The construction and improvement of a democratic system has always been the direction that the CPC has been striving to build since it came to power. The principles of democracy have long been embedded in the CPC's philosophy of governance, and the construction of grassroots democracy is an important part of the development and improvement of a socialist democratic political system. How can we develop and build a good socialist grassroots democracy system? We can look at the example of the successful transformation of the grassroots forces by the Soldiers Committee during the Jinggangshan period. This article intends to take the Soldiers Committee as a starting point, based on the actual situation of grassroots democracy in China, and use the successful historical experience to talk about a little inspiration for grassroots democracy today.
