Friends regret to tell you that this society is not your thing, and you can have a good market. The key is to see how you manage it. If you can manage it well, mud can also be used as gold to buy a rich man with nothing. Now the cognitive ability of China people is so low. Who knew you were a good thing? Nowadays, foreign things are all good things, and cow dung powder is also used as milk powder to drink toxic Evian mineral water for dozens of dollars. Based on these conditions, your patent is worth a lot of money. Although things are good, there may not be a good market. Oh, save it. Wake up.
