Is Hong Zhong Guzheng a Henan brand? How about Zen?

Hong Zhong Guzheng is a brand in Lankao, Henan. As a guzheng, the raw material is the brand of paulownia wood, which is very cost-effective. As far as I know, Zen Heart is made of old paulownia material for more than 20 years, with natural and transparent sound and full charm. Moreover, the annual output of kite-digging is very small, and the price is rising. There is a lot of room for appreciation and excellent collection. I'm happy to accept my suggestion. Thank you. Wish you a happy life!
