Because pianos are durable goods and have a long service life, the most important thing is that the piano production in Japan and South Korea accounted for most of the global piano production capacity in the 1980s and 1990s, and the popularity of family pianos was very high. After Japan's economic decline, the number of battalion commanders in Sanyi, South Korea also surged when the economy took off. Most of them belong to Yamaha and Kawaii in Japan, as well as some second-and third-line brands and Yingchang in South Korea, which are mainly based on Sanyi. With the economic growth and population decline, a large number of pianos have become idle products (low-cost treatment). . . Moreover, the progress and development of China piano industry is slower than that of foreign countries, which leads to the explosive growth of imported second-hand pianos. However, in the past two years, the supply price of second-hand piano chains in Japan and South Korea has generally risen, and domestic piano factories have also made great efforts to improve and develop, and the quality gap is no longer obvious. Some pianos have surpassed imported products. Piano export trade has also increased steadily. In the next twenty years, China may export second-hand pianos, hoping to help you.
