Hello, landlord, I am glad to answer your question about the Songdi maintenance franchise store in Guanle Village. I have a three-ring flute in Miyun, Beijing. The maintenance service is very reasonable and the effect after maintenance is also very good. No matter the hand feel or tightness, the linkage relationship is good, the surface oxidation is also repaired, and the surface bumps and pits are also repaired. These were confiscated, but the overall maintenance fee was charged. I am very pleased with this. After the overall maintenance, He Laoshi kept in touch with me and sent me pictures, which reassured me. Anyone who mailed my flute in Miyun would be worried, but after continuous communication with He Laoshi, my worries were dispelled, and I felt that He Laoshi had a good personality and the price was not expensive. I learned in the chat center that He Laoshi has been engaged in wind music maintenance for more than 20 years. What village is loose? International brands such as Yamaha, Jeppe and Solaisa can repair and maintain the school sound. A classic sentence in He Laoshi's mouth is: Profession is in your hands, and everything goes with fate! I must recommend such a professional and skilled wind music maintenance teacher to you. This is my heartfelt thanks and gratitude.
