Harmani piano is a fake joint venture piano similar to Da Vinci's furniture, and the truth can be revealed by inquiring on China Trademark Registration Online. Hamani enjoys a high reputation because of his excellent advertising, but a really good piano depends not only on the advertisements but also on the history, durability and production technology of the factory. First of all, it is not comparable to the old enterprises such as Xinghai Pearl River in terms of the history of the factory. The piano production is divided into three parts and seven parts, which means that the technical level of the workers in the factory also determines its quality. The longer it takes to build a factory, the better the technical inheritance of workers. Old workers can play the role of "mentoring", new workers can grow up quickly, and the production standards of piano timbre and feel can be unified. When choosing a piano, we should also pay attention to the differences between the north and the south. The so-called Nanqin can't be used in the north, which is mainly caused by the adaptability of wood to different climates. Therefore, if it is used in the north, it is best to consider Xinghai series brands: Hyde K series Chershubert and so on, which are very cost-effective.
