Sister Han is good at farming

Ruan Qingqing got up early and was doing morning exercises in the yard. The brothers Ruan Shixing and Ruan Shifei came together.

"Third sister, grandma asked you to go home for breakfast."

When Ruan Shixing saw Ruan Qingqing practicing Tai Chi, a look of envy was clearly visible on his face.

"Brother, you want to learn?" Ruan Qingqing glanced at him with a smile.

Ruan Shixing tilted his head in embarrassment, "I'm too old to learn this."

"Other techniques may have age requirements, but I don't know how to do Tai Chi. It's good for your health if you practice it after studying. I'll teach you when I have time."

"Hey, third sister, you can't favor one over the other. I am also interested in your second brother!" Ruan Shifei put his hand on Ruan Shixing's shoulder and looked at her with a smile on his face.

"Teach them all!"

"Third sister is really generous. Let's go home and have dinner!" After hearing the satisfactory answer, Ruan Shifei smiled even more.

"Okay! I'll tell Uncle Liu and Aunt Wang about this and then I'll leave."

Before reaching the old house, Ruan Qingqing could smell the special fragrance of mugwort from afar.

After breakfast, everyone started to work according to the simple arrangements made by Mr. Ruan at the dinner table.

Ruan Qingqing and his companions made quite a noise when they entered the mountains. There were four brothers of Ruan Wanjin, as well as Ruan Shixing and Ruan Shizhuang from the first wife, Ruan Shifei and Ruan Shigao from the second wife, and Ruan Qingqing, a total of nine people. They came in a grand procession, attracting a lot of attention.

Everyone they met on the road asked them where they were going. When they heard they were looking for water, they didn't hesitate, rushed back home, searched for it, picked up their things, and followed them.

"Hey, Boss Ruan, what are you guys going to do with all this big fuss?" Chi the hunter's muscles were tense.

"Brother Chi, we are busy! The water in the reservoir is almost gone. Let's go look around and see if we can find some water." Ruan Wanjin explained with a smile.

Chi Jingxiao rushed out from the side, "Dad, I'll go with them!"

Hunter Chi nodded and said to Ruan Wanjin, "Boss Ruan, why don't you take my son with you? He follows me around the mountains all day long. He knows where there are dangers, which roads are safe, and which roads are blocked."

"Brother Chi, this is so kind of you! When we come back, you must come to our house for a few drinks." Ruan Wanjin invited warmly.

"Then I won't be polite!" Chi Hunter grinned.

"If you're being polite, I'm going to go straight to your house and block you, haha!"

"Don't worry! I will definitely get there. But you should be careful when you go into the mountains. It's been dry for almost two years, and water may be hard to find."

"know."

The group of people rushed towards Wudaoling in a mighty manner and entered the deep mountains from Wudaoling.

On the way, Ruan Qingqing asked Chi Jingxiao, "Brother Chi, you've been around a lot, do you know where there's a place surrounded by mountains on three sides?"

"Is there any explanation for this?" Ruan Shixing asked curiously.

"Cuoji land is the most favorable place for finding water. We can easily find water by digging a well in Cuji." Ruan Qingqing explained slowly, "It has been dry for nearly two years now, and it is probably difficult to see clear water. We can only find a way to find groundwater."

"Besides the Cujidi, are there any other explanations for the existence of groundwater? Qingqing, why don't you tell us all about it! We'll all pay attention to it then." Ruan Wanxi looked at Ruan Qingqing leisurely.

Ruan Qingqing thought for a moment, "That's good too. Let's all work together to find a solution. Similar to Cuojidi are 'Two mountains sandwich a lonely mountain, the water never dries up', 'Two ditches sandwich a mouth, there is a spring below', 'Convex mountains face concave mountains, good water is in the concave'."

"This 'an isolated mountain sandwiched between two mountains, where the water often never dries up' refers to an isolated mountain sandwiched between two mountains. Can you find water by digging a well in that isolated mountain?" Ruan Shixing asked, drawing inferences from one example.

"No, it's between the Two Mountains and the Solitary Mountain." Ruan Qingqing broke off a branch and drew a sketch on the ground to indicate to Ruan Shixing.

Ruan Wanxi rubbed his chin and said, "'Two ravines sandwich a mouth, there is a spring below'. Does it mean that there is a small hill sandwiched between two ravines, and it is easy to find water if you dig a well at the foot of the hill?"

Ruan Qingqing shook her head. "It says that there are long mountains on both sides and a short mountain in the middle. If you dig a well at the mouth of the middle mountain, you will get good water."

"'Convex mountain opposite concave mountain, good water is in the concave'. One mountain must be convex towards the opposite side, and the other mountain must be concave inward. The convex and concave are directly opposite each other, so it is easier to get water if you dig a well in the lower part of the concave mountain!" Ruan Shixing said while folding his arms and shaking his index finger.

Ruan Qingqing nodded.

"Not bad!"

Chi Jingxiao scratched his head, "But there is no such landform nearby? There is a landform called Cuojidi, but it is very far away from us. There are several hills between us."

"That won't work! It's too far away. Even if there is water, it's hard to say whether it can be transported back." Ruan Wanjin was the first to object.

Ruan Qingqing thought for a moment, "There are also 'a ravine between two mountains, with water flowing through the rocks', 'mountain mouths facing each other, there is good water under the mouths', 'two ravines intersect, springs are gushing', 'two mountains meet, there is a spring flowing below', 'under the low mouth of a big mountain, dig a well and you will get a lot of spring water', 'when the mountain turns its head, there is a flow', 'a big mountain has a protruding mouth, dig a well and you will find water', 'bays face each other, the water never dries up', 'the terrain is a herringbone shape, with springs hidden in the middle'.

In addition to the consideration of distance, the best water source is the rock layer on both sides of the river valley, which is not suitable. It is difficult to dig a well, and the water taken out is not easy to transport out.

The best water outlets in the following four situations, 'mountain mouths facing each other, with good water under the mouths', 'two ditches intersecting, with springs gushing out', 'mountains turning their heads, with water flowing', and 'bays facing bays, with water not drying up', are all too low in terrain, so even if water can be taken out, it is difficult to transport it out."

The only three options we can choose from are: 'When two mountains meet, there is a spring flowing below', 'When a mountain has a low mouth, dig a well and you will find a lot of spring water', 'When a mountain has a protruding mouth, you will find a lot of water when you dig a well' and 'When the terrain is a V-shaped mountain, there is a spring hidden in the middle'.

"The first part, 'where two mountains meet, there is a spring flowing below', is easy to understand, as the water outlet is right at the junction of the two mountains. How do you interpret the second part, 'where the mountain has a low mouth, there is a large amount of spring water when you dig a well'?" Ruan Wanjin asked Ruan Qingqing, with one hand on his waist and looking around.

"The mountains are connected over long distances and slope down to one end. Groundwater can be found in aquifers at the end of the slope with appropriate topography."

"Shixing, Shizhuang, did you take note of it?" Ruan Wanjin looked at his two sons.

"remember."

"'When a mountain bends, water flows'. If you dig a well in the low part of the mountain bend caused by the mountain bend, you will find water. 'When a mountain has a protruding bend, you will find water in many wells'. This is not difficult to understand. In the middle of a long mountain there is a shorter mountain. If you dig a well in the direction of the bend, you will find water. 'When the terrain is a V-shaped mountain, the spring water is hidden in the middle'... Could it be that the water outlet is halfway up the mountain?"

Ruan Wanxi said in surprise.

As he said that, he hooked Chi Jingxiao's shoulder and said, "Chi family boy, tell us all, which of the things Qingqing mentioned is closest to us?"
