You can go to Xinjiekou and Hufangqiao Musical Instrument Street. There are many musical instrument shops. Only the violin shop sells violins: Haixing Violin Shop.

There are several main indexes of the piano: material, workmanship, paint and sound.

Materials are common now, such as Northeast materials, Sichuan materials and European materials. Europe has the best materials and the best patterns.

The workmanship mainly depends on the workmanship of the piano head, F hole and piano edge.

Paint is very important, you can choose the color you like. I prefer amber and crimson. Paint has special ingredients, and many piano manufacturers spend money to buy paint formulas, and a formula costs tens of millions.

Sound is the most critical and decisive. Without sound, everything is in vain.

The older the violin, the better the sound. It is generally believed that it takes more than 90 years for the violin to produce the best sound, so the old piano is far more expensive than the new one.
