How did Haifeng's red and black flags come from?

After becoming an official, Lei Yuelong cared about the sufferings of the people, distributed food for disaster relief, punished evil and promoted good, which won the hearts of the people. In a few years, he was promoted to the minister of rites. At this time, the eunuch Wei Zhongxian rose to power, ruling in one's hand and ruling in one's hand, and officials and petty officials took refuge in succession. Yuelong was born in honest and frank, but he didn't associate with Wei. Whenever I have leisure, I talk to monks and Taoists. Especially often associate with Zhang Tianshi. The two often talk about the world's major events and the success or failure of ancient and modern times together, and they are very speculative. One day, Tianshi came to Yuelong Mansion and saw that Shang was worried in writing. He asked, "Sir, why are you so sad?" Let's talk about it, how do the mountain people share their worries with you? " Yue Long was full of worries, and hesitated for a long time before slowly saying, "Sir, I didn't know that I just received a letter from home. It is said that the drought in Xinxing State was serious for half a year, when the rain didn't fall, the plows hung high, the seedlings dried up, and the incense was put into my head. How can this not bother me?" Hearing this, the Tianshi nodded silently, only to find that he had a plan in mind and said, "Sir, it's admirable to be concerned about the country and the people, but you don't have to bother about this matter." Your family is not short of food and clothing. " Yue Long was greatly surprised when he heard this. He bluntly said, "Why did Tianshi say this? As an important official, I should share your worries by eating your wealth. When the people are in trouble, how can I eat my salary and live in peace and respect?" Tianshi said quickly, "Sir, don't be angry. At present, floods and droughts are frequent, and swords and soldiers are everywhere. This is God's will, and being original is powerless. However, if there is a disaster on one side, we can try. But I don't know what is the geography of my hometown? Please talk to me, sir. Maybe there is a way. " Yue Long reluctantly replied: "I live in Takakura Tun, which is located in the southeast of Xinxing State, with my back to Matou Mountain. I can't shine on the rivers in the state, and I can't touch the benefits of Luomuqing River in Jiulongchi. Therefore, I am known as" Dry the South ".When the weather is dry, the people are miserable. Tianshi can find a way to save it, please give me more advice. " "Is Matou Mountain a stone mountain or a dirt mountain?" Tianshi asked. "Stone mountain again? What about Tushan? " Yuelong asked. "I will send you a dragon if it is a stone mountain, and it will come out on the ground; If it's a dirt mountain, I'll send you a big black flag, and it will rain when it's dry. " Tianshi explained. "It's a heaped-up mountain," Yuelong said quickly.

Zhang Tianshi lifted his cassock and pulled out a triangular black flag, which was displayed in the wind and grew several times. I saw the dark clouds rolling on the flag, and I felt the wind blowing in my ears. Suddenly, the room darkened and a heavy rain was about to come down. Yuelong was amazed. Tianshi quickly rolled up the black flag and handed it to Yuelong, saying, "This flag can spread clouds and rain, and the lark can test everything. When it rains, just insert it into Matou Mountain and put it away. Remember not to lose it. " Yuelong quickly sent someone to send the black flag back to his hometown, and did as Tianshi told him. It really worked. Since then, Takakura Tun has never been short of water to plant seedlings.
