At night, I went to the Convention and Exhibition Center Square for a walk and saw the National Day car show, which was very beautiful. The "Symphony Silk Road, Ruyi Gansu" car was a color car in the mass parade to celebrate the 70th anniversary of the founding of the People's Republic of China. At 12:26 on October 1, 2019, the color car drove past Tiananmen Square. The colored car consists of Gansu symbols such as ecological Qilian, Benma riding the wind, and present and ancient flying sky. 12 exhibitors dressed in Yugu, Dongxiang, Tibetan and Dunhuang dance costumes danced with music. The color trucks embody the Gansu Silk Road culture, Dunhuang culture, space culture, ecological construction and national harmony, showcase the achievements of Gansu's economic and social development in the 70 years since the founding of New China, and send the blessing of 26 million children of Liaoyuan to the 70th anniversary of the founding of New China.
