    Through this, students see what a business is like. Christian, a 14-year-old student, was really surprised by how hard it was not to make mistakes and to do the transactions(交易). challenge to learn all the information on the stock (存货) lists and remember all the prices of the products," Christian told the newspaper.

    To help them learn about business, they took a class. The class taught students how to use money and some simple business rules.

    The school did a survey on what products students would buy from a school shop. In the future, they plan to sell things made by the students themselves. For example, students can sell their homemade pencil boxes and phone cases.
