What kind of bird's nest is good

There are many ways to classify bird's nests. For example, some are classified according to the origin of the bird's nest, some are classified according to the completeness of the bird's nest, and some are classified according to the taste of the bird's nest. Therefore, whether the bird’s nest is good or not can be judged based on the classification method of bird’s nest. For example, Southeast Asia is rich in bird's nests. In addition, our country's Zhaoqing, Guangdong and Honghe, Yunnan are also rich in bird's nests. The bird's nests in these places are of better quality.

For a large number of people in Southeast Asia who go to caves to pick bird's nests, not only is it extremely dangerous for their lives, but after the caves are picked, nature is also looted. On the cliffs of several small islands in Thailand, many rotting bamboo ladders lead to caves that were once rich in bird's nests. Today, these caves are abandoned and the swallows are nowhere to be found. As the call for protecting nature grows louder, the swallow house invented by the Chinese came into being.

The structures of these swallow houses are no different from ordinary houses, but raising swallows is not the same as raising birds. The swallows are still wild and rely on themselves to find food. The houses are just used to attract swallows to gather together so that they can build their nests in the swallow houses and accumulate a large number of bird's nests. The bird's nests in environmentally conscious birdhouses will not be picked until the young swallows hatch in 18-24 days and can fly in 45 days. The swiftlets return home and build new nests, passing the tradition down from generation to generation. Environmentally friendly house bird's nests are cleaner, smoother, whiter and more delicate than cave bird's nests that grow in harsh environments.

The bird's nest that has not been brushed with starch feels noticeably rough to the touch, while the bird's nest that has been brushed with starch generally looks shiny on the surface. I need to explain here that the presence of gaps does not necessarily mean that the slurry is not applied. Nowadays, more and more counterfeiters still apply the slurry, but they will deliberately leave some gaps. The techniques of the masters who perform the final shaping of the bird's nest during the processing are different. Some masters like to stretch the bird's nest a little wider, while some masters will add an extra shaping process to make the bird's nest tighter, so that it will look more beautiful when wrapped in a gift box.

It should be noted that some people may buy bleached bird's nests. Although the color of this type of bird's nest looks no different from that of ordinary bird's nests, the sulfur dioxide content in the bleached bird's nest may exceed the standard, and there are often a lot of impurities in the bleached bird's nest, so you must carefully distinguish it when purchasing.
