9. December-February in winter, By this time the lobsters had all entered the cave to escape the cold. By this time lobster was already in short supply, It was the highest price of the year, Our situation on the ground is that, By this time, Some idle people took shovels and dug holes everywhere to catch lobsters. At this time, there is usually no water in the pond. Lobster holes are all on the shore, An experienced person can see the lobster hole at a glance. At this time, some of them can be caught and sold. The price is generally twice that of summer. Of course, lobsters with eggs should be put back. It is said above that they basically hatch in October. Why are there still lobsters with eggs at this time? It is because lobsters are of different sizes and do not mature sexually at the same time. At this time, lobsters usually do not hatch until March of the following year because of the low temperature. Our local price at this time is: Lobster with mud collected 18-20% last year, basically with half of the mud, which is about 30 yuan. Taking mud in winter makes people feel that it was dug out of the hole. Even if it is not, it will be pasted with mud, which is basically a hidden rule. Just like selling crabs with ropes, selling 70 people without ropes is too expensive. Taking a few taels of ropes and lowering the price will make it easier for people to accept it.
