In early summer, strolling on the shore of Lake St. Moritz feels "beautiful" and "cool". The south side of the lake is the main city of St. Moritz built on the hillside. It goes down from the sightseeing elevator in the center of the city and passes the trail to the observation deck by the lake. On the other side of the lake, the top of the mountain is snowy, the hillside is green jungle, reflecting the blue sky, the blue lake, that quiet, beautiful lingering. On the east bank of the lake, there is a large shallow rock beach. A yellow-haired girl who accompanied the puppy in the water greeted me warmly to play in the water. She took off her shoes and socks and rolled her pants and legs. She stepped on the water in the lake around 8℃. The cool and cool was unforgettable.
