The expressions "Nanqin" and "Beiqin" were obvious in domestic pianos more than ten years ago, because the technical strength of our country was not strong at that time. Now this problem has been basically solved because of the improvement of wood processing and dehumidification level in various piano factories. In addition, some large-scale piano factories are producing the North-South piano line, mainly because the dehydration rate is different. This problem has been solved! Xinghai B 120LS should be the normal price in the early 10,000 s, but the highest price is 10500. If it is higher than the price, it is not worthwhile to buy Xinghai's piano. Xinghai's piano effect is very poor, and the sound is a little thin!
