Lake Walter is like a sapphire inlaid in Austrian territory. It is clean and shining. Looking at the lakeside, the distant Alps soared into the clouds, magnificent momentum, and the rolling snow ridges and ridges formed the natural barrier of the Walter Lake. Pinghu Lake is like a mirror, and the still fog on the lake is vague, more beautiful and quiet. The changes of clouds and light in the sky paint the lake with a strong oil painting.
