Introduction to Snowflake Lake: Starting from Maoniuping and walking west along the plank road for a short distance, you will reach Snowflake Lake, a light yellow alpine lake where yaks gather to drink water. The water here comes from the highest point of Maoniuping - Yaochi. Although Yaochi is not big, the water quality is clear, and the blue sky, white clouds, snow-capped mountains and green cypresses are clearly reflected in the water.
