Read the following works and complete the questions. More than 20 years ago, Old Song came to this city from the northern mountains. Old Song's mission in the regiment was to deliver, receive, and boil a water boiler. The water was boiling. Old Song stood in the main courtyard and shouted loudly,"The water is boiling!" There was a title for shouting. For this title, Old Song had spent a lot of effort to call the family members of the entire group's cadre, actor, and staff as teachers. No one was disgusted by this title. There was no suspicion of being close or distant, and there was no favoritism. Old Song did a lot of extra work. The people on the fifth floor said,"Old Song, help me carry this can of gas up." The people on the third floor said,"Old Song, the sofa I bought is here. Can you help me?" The women on the first floor liked to knit sweaters, so they shouted,"Old Song, hold the wool for me." Old Song was usually quiet. Sherlie, who was a young singer, was considered his good friend. Old Song only told Sherlie about some family matters. His daughter had married a lazy man from an even poorer place. A few years ago, that person suddenly left Old Song's daughter and a one-month-old child behind. No one knew where he went. Her daughter's life was very difficult, and she had to rely on Old Song to help her everywhere. Time was like an arrow. Old Xia was going to retire, and Old Song was getting older. He began to make mistakes, but the people in the group remembered his character and loneliness and did not fire him. Until one day, Old Song's leg really had a big problem. Old Xia carried Old Song to the hospital on his bicycle. After the doctor examined him, he said that he should have the surgery as soon as possible. It was more important to protect his leg. Old Song asked how much it was, and the doctor said it was about 15,000 yuan. Old Song said to Old Xia,"Let's go back." Old Xia went from house to house to collect money and raised 15,862 yuan for Old Song. Old Song was so excited that he couldn't speak. It was as if his body had fallen into the clouds. Old Song counted the money the entire night. Even an old two-yuan note felt heavy in his hand. After Old Song finished counting the money, he began to think. Was he really going to throw all the things he had just counted to the hospital? He was determined to no longer believe that his swollen left leg was a sick leg. In order to prove his opinion, he performed the difficult movements of an actor's kung fu. Although the form was strange, it was solemn and stirring. These actions made Old Song extremely excited until he fell to the ground. The lights in the reception room were on all night. The next day, Old Song disappeared from the troupe and the city. Old Xia was finally angry, and so were the teachers in the group. Old Song had obviously fooled them by leaving without saying goodbye. Old Xia remembered that Old Song had come to the city through the recommendation of a relative who lived in the city. His relative told him that he went to the county hospital to have his leg amputated the next day after he returned to his hometown. It was cheap there, less than two thousand yuan. What's wrong with having more than ten thousand left? A country bumpkin, a poor daughter, and a poor grandson. Sherlie didn't try to be pretentious anymore. He was just angry and confused. Not long after, someone from the group returned from a performance in the northern mountains and told Sherlie that he saw Old Song at a newly developed tourist attraction. Old Song was sitting in a small iron house selling film. Sherlie was determined to witness the situation of the escaping Old Song with his own eyes. He would use this to stimulate the other party's embarrassment, embarrassment, and guilt. He soon discovered that next to a small iron house, Old Song was holding a pair of crutches and instructing a strong young man to unload the goods. His left leg was empty. Old Xia felt a sour feeling in his heart. He was momentarily unsure if he should go and greet Old Song. Old Song also saw Old Xia and stood there in a daze. All of a sudden, Old Song started running. His healthy right leg dragged his whole body and the crutches forward. He hunched over and bumped into the tourists like a wounded beast. His running dazzled Old Xia. In his trance, he might have somersaulted, spun, and flew. He jumped straight into a mountain path and disappeared in the blink of an eye.
