Please use concise language to summarize the cause, process and result of the plot of "angry words against Yang Zhai"
1. Xiangzi's first car took three whole years and collected 1 yuan. He thought that he could not wait any longer and should buy a car as soon as possible. It happened that there was a car made to order by others and he didn't have the money to pick it up. After bargaining, Xiangzi finally bought the car for 96 yuan. Xiangzi was very excited and decided to buy the car as his birthday and start a brand-new one. One day, someone was going to Tsinghua, and Xiangzi knew that it was very risky to go there, but because of the high price paid by the guests, he and a young bald dwarf took the business by luck. As a result, before they reached their destination, they were captured by more than a dozen soldiers, and Xiangzi's clothes, shoes, hats, rickshaws and even cloth belts tied around his waist were robbed by bandits. He sold the camel on the road and got back 35 yuan. Xiangzi was seriously ill and lay in a small shop for three days. I'm afraid it was in these three days that his relationship with three camels was heard in his sleep or nonsense. When he woke up, he was already a "camel Xiangzi". 4. Angrily, Xiangzi stayed at Mr. Yang's house for a month. Mr. Yang had two wives and a large group of children. At the same time, I have to do chores. What's even more hateful is that the host doesn't treat the servant as a human being, and the accommodation is very poor. One day, after seeing off a female guest, Xiangzi resigned from the job in a rage because the hostess was unreasonable and unbearable. 5. On Xiangzi's lost day, the weather was cold, and Mr. Cao went to see an evening movie with his friends. At this time, Xiangzi and some drivers who pulled the monthly package had tea and chatted in a teahouse. The man has fallen. Everyone brought him back to life and learned about his family. The old coachman and his grandson pony owned their own cars, but their fate was so tragic. Xiangzi was extremely pessimistic and seemed to see his future. 6. Detective Sun blackmailed Xiangzi and his employer Mr. Cao, who told Xiangzi to pull him to Zuo Zhai and sent him home to report. At the door of Mr. Cao's house, Detective Sun took Xiangzi and said that Mr. Cao was a disorderly party. In a daze, he handed over the hard-earned money he had accumulated to buy a car to Detective Sun, and his hopes were dashed. 7. On June 15th, under the scorching sun and heavy rain, the scorching sun was first in the sky, making people breathless; In the afternoon, there was a strong wind and a downpour. In this double day of ice and fire, Xiangzi was not idle, still pulling the cart, and he finally fell ill.
