It is said that the best bird's nest producing area is in Southeast Asia? China is not producing?

Bird's Nest is distributed in Southeast Asia, mainly in Thailand, Viet Nam, Singapore, Malaysia, Myanmar and Hainan Province of China. Among them, the weather and environment in Hoi An, Vietnam are most suitable for swallows to live together, so the quality of bird's nest is the best. Because the output is small and the demand exceeds the supply, the price is more expensive. Because the origin of bird's nest is different, the taste is different. Dongyan mainly comes from Thailand, Vietnam and Malaysia, and the entrance will feel refreshing, slightly rough and not soft enough. Indonesian bird's nest is mainly domestic swallow, which is relatively clean, with less impurities, smoother taste and shorter stewing time. Bird's nest, a specialty of coastal islands, is listed as one of the "eight treasures of seafood". In Yanyan, Qiaotou Town, Huaiji County, Guangdong Province, this rare seafood bird's nest, known as the "Oriental Treasure", is also produced. According to reports, at present, Yanyan has been designated as a provincial-level seabird Jin Siyan rare bird protection area and a provincial-level scenic spot, which is one of the three golden bird's nest producing areas in the world and the only authentic bird's nest producing area in China.
