The best in Lhasa is Lhasa Experimental Kindergarten, which is located on Jiangsu North Road. It's well done. It's big. There are also some private kindergartens. I remember there was a little sun behind Norbulingka. Tibetan children in Lhasa kindergarten are bilingual, while Han children only learn Chinese.
Because after all, there are many Tibetan children here in Lhasa. Most Tibetan kindergartens are bilingual, and Tibetan and Chinese are bilingual. But you can pay attention to Lhasa personnel network, where there will be information.
