On this day, 71 years ago, on December 25, 1954 (December 1, 1954 in the lunar calendar), the Kangzang and Qinghai-Tibet highways were officially opened to traffic. The entire Qinghai-Tibet and Kanghai-Tibet Highways were opened to traffic on December 25, 1954. The ribbon-cutting ceremony for the opening of the Kanghai-Tibet Highway was held at the bridgehead of the Lhasa River Bridge at 10:40 a.m., and the ribbon-cutting ceremony for the Qinghai-Tibet Highway was held on the west side of the Potala Palace at 11:15 a.m. After nine o'clock, Xizang local government officials wearing yellow gowns, teams of various agencies and groups carrying huge banners, and brightly dressed men and women all arrived at the ribbon-cutting places on the two highways. On both sides of the wide road, brightly colored flags and people dressed in various costumes formed a long colorful procession. People are waiting for the arrival of the car procession with infinite excitement. The time to book the ribbon-cutting has arrived amid people's longing. Amid the sound of music and firecrackers, General Zhang Guohua, commander of the Xizang Military Region of the People's Liberation Army, cut off the colored silk on the Kanghai-Tibet and Qinghai-Tibet highways. The motorcade slowly passed through the towering colored archways and drove towards the jubilant crowd. The cadres in charge of road construction, heroes and models on the cars waved to each other with the welcoming masses. Clapping, cheers and singing were heard, and at the same time, firecrackers were ringing, and the artistic and artistic team wearing makeup danced. People presented hada and bouquets of flowers to the statue of Chairman Mao on the float, the cadres in charge of road construction, and the heroes and models, snow-white hada, bright red bouquets and confetti decorated the car with colorful colors.

At 12 o'clock, two motorcade teams met in front of the Potala Palace.
