In celebration of the 60th anniversary of the founding of the Xizang Autonomous Region, CGTN is launching the special series "A Journey to Prosperity." The program highlights six decades of modernization and transformation in the region. By the banks of the Yarlung Zangbo River, Sanyou Village has opened a senior daycare center, known by locals as the "Happiness Station." CGTN's Xu Yanwen takes us inside.
