Siheyuan, integrating everything, cultivating the city

As time went by, Li Xiangqian continued to pay close attention to the growth of the potatoes. He would go to the vegetable garden every afternoon to check, record the changes of the potatoes, and make adjustments according to the advice of the old farmer. His mood gradually calmed down in the process. Although there were still many challenges, he began to learn to find fun and a sense of accomplishment in these challenges.

Li Xiangqian was still worried about the situation in the potato field. Although the pests had been reduced after treatment, there were still some signs that made him uneasy. In order to completely solve the problem, he decided to ask for more help. He thought of an old friend in the village, He Yuzhu, a farmer who was quite experienced in pest control. He Yuzhu was known for his ability, especially when faced with various farmland problems, he could always find effective solutions.

"Let's go find He Yuzhu now. His experience may help us solve this difficult problem." Li Xiangqian said to Xiao Ming while sorting out the tools in the vegetable garden. He had a glimmer of hope in his heart, hoping that He Yuzhu could bring some new ideas or methods.

Xiao Ming nodded, quickly packed up his equipment, and followed Li Xiangqian to He Yuzhu's home. The two did not talk much along the way, each of them thinking about the future of the potato field.

When we arrived at He Yuzhu's home, it was already getting dark. He Yuzhu was sitting in his yard, half leaning on a wooden chair, smoking leisurely and enjoying the tranquility of the evening. When he saw Li Xiangqian and Xiao Ming coming, he smiled.

"Li Xiangqian, how come you have time to come to see me?" He Yuzhu stood up and greeted him.

"Brother He, the problem with the potato fields is getting worse. I'd like to ask you to come and help." Li Xiangqian said politely, with a bit of expectation and anxiety in his tone. "We have tried some methods, but the results are not very good. I hope you can come and take a look."

He Yuzhu nodded, a look of serious thought on his face. "The pest problem in potato fields is indeed very difficult, especially this kind of insect that spreads quickly. Come on, take me to have a look."

Li Xiangqian and Xiao Ming took He Yuzhu to the edge of the potato field. On the way, Li Xiangqian described the current situation in detail, including the measures taken before and the pests observed. He Yuzhu listened carefully and nodded from time to time to show his understanding.

Arriving at the edge of the potato field, He Yuzhu began to carefully check the condition of each potato plant. His movements were steady and meticulous, as if he was facing a complex problem. Li Xiangqian watched silently from the side, full of expectations. He hoped that He Yuzhu could find the crux of the problem and bring them a new solution.

"These bugs do seem to be troublesome," He Yuzhu stood up with a serious look on his face, "However, the methods you used before are not unreasonable. It's just that some additional work may be needed."

Li Xiangqian was shocked and asked anxiously, "What should we do then?"

"First, we need to find the breeding source of pests more accurately." He Yuzhu pointed to a corner of the potato field. "The insects here seem to be concentrated in a few places. Maybe something in the soil attracts them. We can try to apply some special treatments to these places."

Li Xiangqian listened carefully, and a new hope surged in his heart. "What should we do specifically?"

He Yuzhu pondered for a moment, "We can add some special agents to the soil and use physical methods to clean it. Another point is to conduct regular inspections to detect new pests in time. Only in this way can we effectively control the speed of the spread of insects."

Li Xiangqian nodded repeatedly, "Then let's get started now."

"Yes." He Yuzhu agreed and began to take out various tools and medicines from his bag. Li Xiangqian and Xiao Ming also quickly cooperated, and everyone began to divide the work and cooperate according to He Yuzhu's instructions.

As night fell, work on the potato field continued. Under the light, everyone's faces were covered with sweat. Although Li Xiangqian was tired, he felt a little relieved because he saw substantial progress. He knew that this effort might improve the situation.

During the busy process, He Yuzhu would stop from time to time to observe the changes in the potato fields and give some new suggestions. His experience and expertise benefited Li Xiangqian a lot and also gave him more hope for the future of the potato fields.

"Xiao Ming, help me spread this medicine evenly on the affected area." He Yuzhu commanded, his voice with a hint of fatigue, but more of confidence.

"Okay, Brother He." Xiao Ming responded and followed the instructions carefully. His heart was also full of hope. Seeing the cooperation between Li Xiangqian and He Yuzhu, he felt that his efforts were meaningful.

As time went by, the work gradually came to an end. Li Xiangqian stood by the potato field, looking at the land that was gradually being cleaned up, and a sense of relief surged in his heart. He knew that although the problem of pests had not been completely solved, at least they had taken an important step in the right direction.

"Thank you, Brother He." Li Xiangqian said sincerely, "Your help this time is very important to me."

He Yuzhu smiled and waved his hand, "You're welcome. I'm only willing to help because we're friends. Just keep going, and the problem will be solved."

"Xiao Ming, thank you for your hard work." Li Xiangqian turned to his nephew, his voice full of gratitude.

"It's okay, Uncle Li." Xiao Ming responded with a smile, "We will work together and the problem will be solved."

After several days of intensive treatment and adjustment, Li Xiangqian made some improvements to the potato field, but the problem was still not completely solved. He knew that it would take time to completely eradicate the pests, and perhaps more effective methods would be needed. He secretly vowed in his heart that no matter what, he would restore the land to its original state.

At this time, Li Xiangqian's friend Xu Damao approached him. Xu Damao was a middle-aged man with a straightforward personality and sharp words, often known for his humor and boldness. They had made many bets and competitions, and always maintained a "competitive" friendship.

"Li Xiangqian, how is your potato field doing?" Xu Damao started talking as soon as he entered the door, with a teasing smile on his face. "I heard that the insects have been causing quite a lot of trouble recently. Are they so anxious that you don't even have time to drink water?"

Li Xiangqian gave a wry smile. Although he still felt stressed about the pest problem, he had gotten used to Xu Damao's teasing. "Yes, the pest problem is really giving me a headache. But I'm already taking measures to solve it step by step."
