On almost 3,000 meters above sea level, Ta Chi Nhu Peak in Yen Bai Province is home to pink flowers named chi pau, which means “unknown” in the local language. Late autumn, around October and November, is the season of this flower. Blooming pink, the little flowers with five petals look like stars. The whole area of Ta Chi Nhu turns into a vast pink field when the flowers are in full bloom. Chi pau flowers in harmony with fog and white clouds and some horses strolling around in the background give a spectacular view.
