How about Xingyun brand guzheng?

It seems to be the largest musical instrument manufacturer in southwest China. The factory is located in Chengdu and is not well-known in China. But it is widely used in southwest China, especially in Chongqing, Sichuan and Guizhou. Although the popularity is not high, the zither timbre of Xingyun is quite good, especially the golden string zither, which is a major feature.
