Chinese President Hu Jintao (3rd R) attends a class at Fangcaodi International School in the Chaoyang District of Beijing, May 31, 2009, a day ahead of the International Children's Day.

Chinese President Hu Jintao visited two primary schools in Beijing on May 31, joining children in language classes, games and kite painting, and wishing them a healthy and bright future.

Hu made the visits on the eve of the annual International Children's Day, which falls on Monday and will be celebrated by about 250 million children under the age of 14 across the country.

Hu first went to Jushan Primary School, where 90 percent of some 700 students are children of migrant workers from outside the Chinese capital.

The boarding school is seen as a model of equal and quality teaching for migrant children.

Hu joined first grade children, who were learning Chinese idioms such as "When you drink water, think of its source." Satisfied with their understanding, Hu told them to learn to be grateful for what they enjoyed and to study hard.

During a handcraft session, the president was shown works made from recycled materials and paper. He happily joined several students in finishing a mosaic map of China, using pieces of egg shell.

"This is a good idea to use recycled materials to make handcrafts. I hope you become more aware of saving natural resources and environmental protection," Hu told the excited kids.
