In my opinion, the subject is a good question, so that young people who have never lived in the past can follow our memories and feel that life at that time was not easy. They should stand from a historical perspective, that is, put themselves in other&;s shoes and complain and be angry blindly! I was born in the early 1960s. It can be said that I have witnessed the changes in our country since I was born, and only then did I realize that the development of our country to this point was very hard-won, and I will cherish today&;s hard-won happiness and harmonious and peaceful life. I was born in the hardest time since the founding of the Republic, and grew up in a decade when I didn&;t pay attention to knowledge. I can say that I have tasted enough of the sweet and sour life. It also witnessed the whole process of the country from scratch, from poor to rich, from weak to strong. Only those who have experienced that era will know how happy and cherished it is today. I joined the work in 1984, and I was in the early stage of the replacement of the old and the new. Because I was young and active, I was eager to learn, and a large part of my business trip fell on my head. At that time, I naively thought that this was a leader&;s respect and gave me an opportunity to exercise. I was really grateful. Later, I learned that the subsidy standard for business trip was quite low, and people were still hard, even thankless. In the past, when traveling on business, you had to do several homework. First, you had to be prepared for hardship. The transportation facilities were quite backward, and it was common that you couldn&;t buy tickets for a certain place or other means of transportation for a week. Often can&;t stay in a hotel, have a ticket without a seat, all the transportation is late, hungry, all kinds of life inconvenience is common. Second, bring a letter of introduction, food stamps and enough cash. In the past, eating and staying in hotels were mainly state-owned, and I was lucky to have a place to live. I still want to be so picky and dreaming today. If the service attitude is not good, you can&;t say it. If the service quality is poor, you have to break your teeth. Otherwise, it&;s none of his (her) business if you have one more and one less. If you don&;t have a formal letter of introduction, people won&;t take you in. Because there are too many uncertain factors when going out, experienced business travelers should prepare many blank letters of introduction with seals in case of emergency. In case of special circumstances, it is necessary to open the letter of introduction to the superior units of the city, province and country. For example, if you buy a plane ticket, you can&;t buy a plane ticket without a letter of introduction from a unit above the county level. For another example, a county-level unit wants to go to a unit above the county level to investigate a case. Without a letter of introduction from a unit at the same level or above, people still ignore you, so who can you do? The third is to have a good temper. In the past, when you were on a business trip, as long as you stepped out of the house, you could say that you couldn&;t help it. Transportation, communication, accommodation, including enough travel expenses, were often stolen. It was really difficult, so it was better to go out. I was on a business trip from Hunan to Hubei in, because I had to ask my boss for instructions. I called in the morning and didn&;t get through until seven o&;clock in the post office, and the call quality was quite poor, so I had to improvise some problems myself, otherwise, it would be thankless. The letter of introduction is only a small part of going out. For example, if you have money and no food stamps, you can&;t eat. For example, staying in a hotel is the biggest headache.The problem is that it&;s too far from the station, and it&;s very inconvenient to transfer. It&;s too close to the station, not to mention expensive, and it&;s not safe and hygienic. Unlike today, it&;s not surprising to live in a single room or a standard room. In the past, there were five or six people in one room, or even a dozen people. So many digressions, just want to make young people who have not experienced the past life feel that today&;s happy life is hard-won, and also feel that through the development and progress of the country for more than 30 years, they feel that now they are not only rich in materials, thoughtful in service, convenient and complete in service facilities, but more importantly, convenient and safe! Grateful for reform and opening up, grateful for national development and social progress!
