How much do Erhu masters and their disciples know?

Personally, I haven't used erhu much, so let's talk about my use! Master Jiang Jianhua's erhu is soft and delicate, and its reflection is very sensitive. The only fly in the ointment is that the voice is a little low and lacks penetration. Master Wang Guoxing's erhu is sweet and soft, with sensitive reflection, but with a slight nasal sound. Lu's erhu is bright and sensitive. The high-pitched area is good, but it's expensive. Master Wan Qixing's erhu has a strong traditional flavor, reasonable cost performance and exquisite workmanship. Jiang Jianmin's erhu sounds are more modern and old-fashioned. Suitable for playing modern violin transplant music. Master Zhou Jian's erhu voice is also traditional, but it is loud and penetrating. Master Lu Jianhua's erhu timbre is a combination of tradition and modernity, with delicate elements in rough and wild, good penetration and too expensive. This is my own erhu, and the others have never been used. Please add it. [ ]
