Duan Jiayang, a 12-year-old student of a primary school in Fujian, learns the skills to take care of vegetable fields.

"I learned how to place the mulch film（地膜）, "he says. "It's not easy."

In China, many parents pay much attention to their children's good marks, but vocational（职业的）skills have little been cared.

"Some parents do everything for their children", says Yan Mei, an official in the primary school, adding that many students are short of the basic skills needed in their everyday lives. "For example, "Yan says." Some parents would do the school's general cleaning instead of their children. "

Since March, 2020, the governments have launched（推行）a lot of policies, requiring that colleges, middle schools and primary schools pay more attention to teaching students practical skills.

Following these policies, the primary school launched an "agricultural （农业的）class base" on one of its school yards. Students plant fruit and vegetables on an area of land about 4, 000 m in size.

"In the days coming up to the May Day holiday, students of various grades at the school worked together in the fields, "says school principal Yang Bo. "They planted watermelons, carrots and corns. May Day, also known as Labor Day, is celebrated on May lst in China. "

The school hopes that students will understand the food is quite precious（珍贵的）so that they will better realize the difficulties that their parents went through.
