On a rainy weekend in March, Hangzhou in Zhejiang welcomed a special group of guests. From March 23 to 24, 31 young people from 30 countries and regions gathered in the city, sharing their experiences and exchanging ideas at the Belt and Road Youth English Speaking Competition.

During this competition, young contestants had conversations about each other's cultures. They also shared their impressions of China and its development so far. In the final, six contestants gave speeches with a theme of The Great Truth is Simple.

Contestant Nicol Yong Jia Jia from Malaysia won the championship. She said she thinks people's "great truth" comes from their hearts. By this, she means that people can look at negative situations in a positive light. For example, she is rather short, but she looks at her height in a humorous way. "I actually think I'm pretty tall. You are just taller," she said.
