The worst kind, of course. There are instant sea cucumbers now, which are very cheap. Some of them can buy one for only a few yuan. Think about it and you will know that they are definitely not good. After screening, I can't bear to throw it away. If I catch it in pure feed for a few months, it will be made into instant sea cucumber. I want to buy all the cheap ones. Hehe, don't be greedy for cheap for health. Instant sea cucumber is harmful.
