If Teacher Xu Dajun and his family don't buy a house, they will have a hard time. The small vendors downstairs shout loudly until midnight, which directly affects the rest and academic performance of his son Xiaojun. His wife Wang Fanghua feels that she has been stuck in a tube building with Lao Xu for most of her life. Taking advantage of the school's plan to issue housing subsidies, Lao Xu and his wife discussed that they would use the 150,000 yuan in savings and the 100,000 yuan that the school would soon issue to mortgage a 90-square-meter house near the Third Ring Road. Once the family's major decision was made, Lao Xu's whole family was mobilized to look at houses together. From the Third Ring Road to the Fourth Ring Road, from the Fourth Ring Road to the Fifth Ring Road, Lao Xu felt that he could not retreat any further. If he retreated any further, he would have to go into the mountains, and if that happened, it would be inconvenient for his son to go to school in the future. But he had to retreat! After looking at houses for a few weekends, Lao Xu felt that the price was out of control. The advertisement clearly stated that the starting price was 6,000 yuan, but as soon as he talked to the sales lady, the price increased by 500 yuan. The sales lady said that if you don't buy it today, it will increase tomorrow. The sales lady was right. While Lao Xu was hesitating and depressed, the prices of the buildings that Lao Xu had seen before were all rising. It was at this time that the school principal called all the teachers for a short meeting. At the short meeting, the principal said that under the premise of not violating national policies, the maximum one-time housing subsidy issued by the school would not exceed 50,000 yuan. Specifically for Lao Xu, it was only 30,000 yuan. 30,000 yuan is 30,000 yuan. If you don't buy a house now, maybe one day the school will change its leadership and even the 30,000 yuan will be gone. Lao Xu was determined. He reluctantly sold a set of stamp albums in his hand and took the money to a building called Chongxingyuan to queue up to buy an affordable house. Lao Xu was not prepared and thought that he could just pay the down payment with the money. Who knew that the queue was so long that you could never see the end of the dragon. After two consecutive nights, Lao Xu finally realized how difficult and hard it was to buy a house. Finally, it was Lao Xu's turn to choose a house. Lao Xu, who had been teaching for a lifetime, lied this time and asked the developer for a small apartment that he thought was enough for a family of three. However, before the family could get over their joy, Dajun's mother fell ill because she was worried about her son's house purchase. When his mother came out of the hospital, Lao Xu felt that the house should not be bought. In case something happened to the old man and the old lady one day, the emergency money must be available. Lao Xu thought so and did so. When Lao Xu sold the affordable housing number, the old man and the old lady's bungalow in the second ring road finally waited for demolition. A year later, Lao Xu's family of five moved into a spacious and bright new house. The environment around the new house is particularly good. There are neat fields downstairs and the Yanshan Mountain not far away.
