On April 10, more than 60 students from the Middle School Attached to Northwestern Polytechnic University took part in the One Yuan Metropolis Survival.

Some made use of their talents by singing and dancing in parks or shopping malls. Many people who walked by took notice and helped them. Zhao Jincheng, 14, drew pictures and made paper crafts(手工). “This showed it's important to learn a special skill,” he said.
