What is the zodiac sign for hanging mosquito nets and lighting mosquito coils?

It is said that somewhere in the south, there is a mosquito family, which has been doing well with the secret recipe handed down from ancestors. Today, the mosquito family has reached the twentieth generation. Every day, I see him setting up a tent under the big banyan tree, and he sits in the shade to collect money. Outside the tent, there is an ancestral sign that reads: A wonderful recipe for killing mosquitoes, used for a lifetime, and charged 10 RMB each time. Outside the tent, there has been a long queue. Many customers come from afar just to find a magic formula to deal with annoying mosquitoes. All the people who entered the tent came out in less than two minutes. Some people smile and show great happiness; Some people are thoughtful and have a deep understanding of the recipes handed down from generation to generation; Some people look naughty, like a student who was beaten by a teacher on the spot; Someone left in a hurry to practice the magic formula given by the master. One day, A Niu, a dizzy young man, came to ask for help, but as soon as he got out of the tent, he shouted, "liar, liar, what a master of shit. Is this a magic formula? My mother says that every day. Deception, deception. " A Niu left, but people didn't. They waited for the next person to come out and verify. As soon as thin Alfred came out, people rushed in and asked noisily, "Is that master a liar?" What did he say? " Ah Fu gave a thumbs-up and said, "Gao! Really high! Useful in this life, and useful in the next life. Worth it, worth it. " People have settled down a lot. The next customer is a fat man, Shou. He came out of the tent and shouted excitedly, "I hate hearing wise words late." If I had visited the master earlier, I wouldn't have been tortured by mosquitoes for half my life. " Someone asked uneasily, "Will what A Niu said be true?" Shou glared and said, "Do you believe what that little bastard A Niu said? He wants to keep the secret recipe for himself, but he is not kind. If the master doesn't have a skill, can he pass it on for dozens of generations? " Later facts showed that everyone who came out of the tent left with a satisfied smile. Many years later, the master was seriously ill and was about to die, so he called his only son to his side and said to him, "Over the years, we have no worries about food and clothing, relying on the magic weapon of our ancestors, and now my father has taught you." First, everyone is unwilling to bear the failure, even if they are fooled, they are stubborn; Second, people don't want others to be better than themselves. If he is cheated, he wants others to be cheated like him. Third, no one admits that he is a fool. As long as you flaunt yourself as the truth, no one will oppose you or even carry it forward for you to prove that you are not stupid. You must remember it firmly. " The son asked, "What's the use of remembering these?" The master said, "You must understand human nature, so that you can use them easily and the family magic weapon can be passed down from generation to generation." Seeing that the master was out of breath, his son urged him to say, "Dad, tell me quickly, what did you say to the customers in the tent?" What is the secret recipe for killing mosquitoes that they are willing to spend money on? "The master swallowed his last breath and said," Hanging mosquito nets won't make mosquito-repellent incense; "If you order mosquito-repellent incense, you won't hang mosquito nets."
