It was a summer afternoon in the countryside. Wan Bo, a university student, was painting while his classmate Tang Qi was making a wooden box by the river. A little riding on a rocking horse caught their eye by chance. It brought them back to their childhood, warm and happy.
"Why not try to make one by ourselves?" said Wan Bo. "You are good at making things and I am interested in painting."
"Actions speak louder than words," Tang Qi said. Then, the two young men began to collect some information about it. During those days, watching videos about caring(雕刻) and shaping wood into horse shapes on the Internet became an important part of their life.
Several months later, a wooden rocking horse appeared. They felt so excited that they put the picture of it on the Internet right away. To their surprise, it attracted lots of people's attention and some even hoped to order one.
The two young men thought it might be a good chance. They sent some forms to the customers to make a survey. According to the result, they made each customer a special rocking horse. These horses were quite different from those produced in other factories, and they soon became popular among the customers.
In the first year of their new hobby, Wan and Tang made thirteen rocking horses. Sometimes, they also repaired rocking horses for people. They made the old ones look new again. Wan and Tang helped those people bring back many happy memories.
Their hobby has now become a successful and busy business.
