As the Dalai Lama turns 90, Tibet remains silent under strict Chinese control. A BBC report from Aba, Sichuan province, reveals pervasive surveillance and suppression of Tibetan culture and religion. Monks express concerns about restrictions on religious practice and education, enforced through state-run schools teaching Mandarin. China's announcement that it will choose the next Dalai Lama contradicts the Dalai Lama's own succession plan, highlighting the ongoing tension between Tibetan identity and Chinese authority. The situation reflects decades of suppression and assimilation efforts by the Chinese government.
