     For most students in universities, 20,000 yuan is a big sum. But Xiao Wang paid the money soon after

she learned that she could change to the popular Economics Department.

     But by paying 20,000 yuan with the help of her parents, Xiao Wang can study the economics major she

prefers. "It is difficult for graduates (毕业生) in chemistry to find a good job in recent years," she said. Xiao

Wang is only one of the many freshmen that pay to change to popular majors. Many universities throughout

China offer similar services. The charge for changing majors are from 5,000 yuan t0 80,000 yuan, according

to a recent report on the Yangzi Evening News. The fee (费用) is decided by university authorities based on

the popularity of each major, the report said. The most popular majors include computer science, law, finance,

information engineering and foreign languages.

     A saying popular among students may explain the phenomenon (现象). Studying a good major is much

better than studying in a famous university.

     Some educators warn students against rushing blindly to today's popular majors. They may not be popular

years later, the China Youth Daily said. But it seems that many students are career-oriented (以职业为宗旨的),

instead of being interest-based.

     Freshmen are allowed to change to other departments, according to rules of the Ministry of Education. But

there is no official rules on the charges. In spite of the high charges, demands to change majors are still

increasing. The paper said about 100 students in the English language department of a school in Harbin changed

from other departments. The department planned to admit only 50 freshmen this year.

     These charges have become a big income for some universities, the paper said. It is expected a normal

school in Harbin will get an income of 30 million yuan this year.
