阅读理解。 Sichuan (China Daily)-The beginning of 2007 will see another mass of graduates fresh from the campus hunting for jobs. Sichuan University has done something special to help its graduates. One morning last month, a lady stopped her Porsche (保时捷豪华跑车) in front of the students' canteen (食堂). She stepped out of her expensive car and began to polish shoes for the students who were passing by. Later it was discovered that she was a special lecturer who had been invited to talk to students on career development. Li Hui, 42, started from scratch (白手起家) in 1998 and has expanded her shoe-polishing service from a single one-person stand on a street to a chain of 2,000 stands that operate in supermarkets, hotels and office buildings. Li Hui said, 'Apart from the existing and advertised job opportunities, there are plenty of other ways that people can try to make money. There is nothing ignoble if you are doing an off-line business on your own, such as car washing, house cleaning, shoe polishing, etc.' It is to be hoped that such a successful grassroots woman as Li Hui will give the coming rush of job hunters an insight into the job market in another way. 1.
