LHASA -- The year 2021 was extraordinary for Southwest China's Tibet autonomous region, characterized by a visit by the country's top leader, grand celebrations marking the 70th anniversary of its peaceful liberation, and all-round progress in various domains.

The following is a lexical walk through some of the major landmarks and achievements of the region throughout this important year:
