In 2007, the Ministry of Education published the list of national key construction disciplines in colleges and universities, which were divided into national first-class key disciplines and national second-class key disciplines according to their importance. Among them, there are 45 first-level disciplines, two disciplines 175. On the list, we see many grassroots majors, such as agriculture and forestry (such as agronomy, forestry and crop science), geology (such as geology and geography) and animal husbandry (such as animal husbandry and veterinary medicine) ... These majors generally have more state capital investment, and most of them are located in key universities, such as "21kloc-0/engineering". For those students who have the ability to be admitted to key universities, this extensive list of key construction disciplines undoubtedly provides you with more choices. Moreover, these national key disciplines are often the key disciplines of colleges and universities, which are very reassuring in terms of teachers, courses and hardware facilities. The tuition fees of key universities are generally high, ranging from 5,000 to 6,000 yuan/year, but the "sisters" of our grassroots families are generally 3,000 to 4,000 yuan/year. For example, the tuition fees of finance, biological science and vehicle engineering in China Agricultural University are all 5,000 yuan/year, while the tuition fees of key construction majors such as plant production, animal science and animal medicine are only 3,000 yuan/year; The tuition fees of computer science and technology, automation, transportation and other majors in Nanjing Agricultural University are 4,600 yuan/year, while the tuition fees of plant protection, agronomy and animal medicine, which are key national construction, are only 2,500 yuan/year.

For poor students, if they are admitted to a key university, it is equivalent to eating a reassurance. Because the state has invested heavily in key universities, the financial resources of the universities are relatively strong and the funding system is relatively perfect. Many key universities have the slogan "Poor students can't afford to go to school". According to the national regulations, the school allocates special funds for tuition remission for students with difficulties every year. Usually, the school has many kinds of awards and subsidies, most of which come from donations from some enterprises or alumni. For example, the scholarships set up by China Agricultural University for undergraduates are divided into single scholarships and special scholarships, and the comprehensive award coverage rate is nearly 60%. Individual scholarships are set up by the school for undergraduates with excellent academic performance, including principal scholarship, scholarship with excellent academic performance, scholarship for scientific and technological innovation, scholarship for spiritual civilization, scholarship for social work, scholarship for problem activities, scholarship for learning progress and scholarship for endeavor. In 2006, the reward amount was 3.996 million yuan. Special scholarships are established by the government, social organizations or individuals in schools. Including National Scholarship, Hong Kong Chongzhen General Association Education Award Fund, Zigen Scholarship, Baosteel Education Fund Scholarship, An Lifang Scholarship, Dupont Scholarship, Samsung Agricultural Talent Training Scholarship, Hope Project-Kerry Grain and Oil Scholarship, New Hope Scholarship, Coca Cola Scholarship, Hekang Agricultural Education Research Fund, Zhang Jiguang Scholarship, Chaoyang Education Fund Scholarship, Yang Scholarship, Excellent Scholarship for Ethnic Students, etc.

Therefore, for those candidates who have excellent grades and have the ability to be admitted to key universities, we suggest that you focus on your interests, and then give due consideration to the region and living expenses, and feel free to choose your favorite major. Strong student support from key universities will definitely guarantee you to study with peace of mind for four years. If you don't have a clear interest goal, you may wish to adopt the principle of "choosing a place first, then choosing a school, then choosing a major". For example, Xiaoding, a poor student, used this method. First, Wuhan with low consumption level but good educational resources and level was selected among many cities, and then Huazhong Normal University with low tuition, perfect student aid system and excellent academic atmosphere was selected. Finally, he aimed at the physics major of China Normal University.
