Help yourself. I suggest you buy ginseng, ginseng, ginseng and topaz, all of which are very good.
Quality identification of sea cucumber: 1, salt-free: don't be covered with salt (but sea cucumber is seafood after all, and it is normal to have a slight salty taste). This is because unscrupulous merchants add salt to increase their weight.
2, sugar-free: like salt, it is also to gain weight. Just lick it. A little sweet is also sweetened, but seafood can't be sweet.
3, dry feet: not wet, not soft, dry enough sea cucumber is very hard, no moisture, those soft and wet are not dry, the weight is biased.
4, tasteless: Some sea cucumbers will have a bad smell after adding other things, which is very unpleasant. Normal sea cucumbers have a fishy smell.
5, no decay: this can be seen with the naked eye.
