Through the exhibition of the West China Trade Fair, we found that the tricycle industry has a good development prospect. At present, our manufacturing technology is becoming more and more mature. In the future, under the leadership of the Party and the government, we will keep pace with the development of the times, bring forth the new, and combine technology with modern technology to make Dayang three rounds more brilliant. In addition, we look forward to serving more people in the near future
