How did Haifeng get the red and black flag?

After Lei Yuelong became an official, he cared about the sufferings of the people, released food for disaster relief, punished evil and promoted good, and won the hearts of the people. A few years later, he was promoted to be the minister of rites. At this time, Wei Zhongxian, the eunuch, gained power, and officials and beadles took refuge in one after another. Yue Long was born honest, but he didn't associate with Wei. Whenever I am free, I chat with monks and Taoists. Especially often associated with Zhang Tianshi. The two often talk about world events and success or failure in ancient and modern times together, which is very speculative. One day, I came to Yuelong House and saw Shang writing something there. He asked, "Sir, why are you so sad?" Let's talk about it. How did the villagers 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 I just received a letter from home. It is said that the drought in Xinxing Prefecture is serious, and it doesn't rain for half a year. The plough hangs high and the seedlings are withered, and the fragrance enters my head. How can this not bother me? " After listening to this, Shi Tian nodded silently, only to find that he had a well-thought-out plan. He said, "Sir, it's admirable to worry about the country and the people, but you don't have to bother about this. "There is no shortage of food and clothing in your family." Yue Long was very surprised when he heard this. He said bluntly, "Why did Shi Tian say that? 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 a peaceful and respected life? " Shi Tian quickly said, "Sir, don't be angry. At present, floods and droughts are frequent, with swords and shadows, and the war is in chaos. This is providence, and originality 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 replied helplessly: "I live in Takakura Tun, located in the southeast of Xinxing State, with my back to Matou Mountain. I can't see the rivers in the state, and I can't touch the benefits of Luomu Qinghe in Jiulongchi. Therefore, I am called "Gannan". When the weather is dry, people are in pain. Shi Tian can find a way to save it, please advise. " "Is Matou Mountain a rocky mountain or a dirt mountain?" Shi Tian asked. "Stone mountain again? What about Tu Shan? " Yue Long asked. "If it's a rocky mountain, I'll send you a dragon, and it will pop up on the ground; If it is a dirt mountain, I will send you a big black flag, and it will rain when it is dry. " Shi Tian explained. "This is a heaped-up mountain," Yue Long said quickly.

Zhang Tianshi lifted the cassock, pulled out a triangular black flag, fluttered in the wind and grew up several times. I saw dark clouds rolling on the flag, and I felt the wind blowing in my ear. Suddenly, the room darkened and a heavy rain was coming. Yue Long was amazed. Shi Tian hurriedly rolled up the black flag and handed it to Yuelong, saying, "This flag can spread clouds and rain, and larks can measure everything. When it rains, put it in Matou Mountain and put it away. Remember not to lose it. " Yue Long soon sent someone to send the black flag back to his hometown and did as Shi Tian told him. It really works. Since then, Takakura Tun has never been short of water to plant seedlings.
