Beijing, April 10 (Youth.cn) - On April 9, 2026, in Cengong, Guizhou, herons perched on trees. In recent years, Cengong County in the Qiandongnan Miao and Dong Autonomous Prefecture, Guizhou Province, has continuously strengthened the systematic management and protection of mountains, rivers, forests, farmlands, lakes, grasslands, and sands. The ecological environment has steadily improved, attracting rare bird species such as egrets, purple herons, and cattle egrets to forage, breed, and inhabit the area. Photo/CFP
