Don’t believe what these people say, they are all supported by the music shop. It is also sold to more than 40 countries around the world. Just play it as an OEM piano. As of 2019, Pearl River Piano has been exported to 112 countries around the world. Kaiserburg’s KA Artist Series has already surpassed Japan’s original Yamaha and Kawaii. In 2004, a European branch was established in Munich, Germany, selling Chinese-made Rietmuller. The original Rosser factory had already closed down, and was acquired by PETROF. In China, Helen does the OEM, and Xuancheng uses PETROF's technology. The drawings mislead customers by saying that it is a joint-venture piano. Most of the piano's parts are common parts and must be imported. What is the joint-venture? Pianos are all about the selection of materials and craftsmanship and the finishing and debugging by technicians in the later stage. Go and take a look at the original PETROF. You will know the timbre if you look at Rother. It is like Lafite and Lafite Legend under Lafite. The main brand Lafite sells for more than 10,000, and its OEM sub-brand sells for several hundred, and the profit is still very high. The profit of this kind of piano is very high. It is made in China for the Chinese market. This piano is not on the international piano quality rankings. If you buy PETROF, buy the one made in the Czech Republic. Don’t fool people with OEM pianos like Rosser
