In Tibet, some embrace their native language even under China's sweeping new 'ethnic unity' law

In Lhasa, Tibet, 73-year-old retired nurse Kalsang Lhamo is learning to write Tibetan calligraphy at a local center, despite having spoken the language all her life without learning its written form.

This personal effort to embrace the native language coincides with the implementation of China's sweeping new 'ethnic unity' law, which places pressure on regional linguistic practices and cultural expression.
