In Jiuzhaigou in winter, there are few pedestrians, the air is fresh and bright, and the sound of water, wind, birds, leaves, grass and soil come with the wind. Jiuzhaigou always changes with different seasons and different altitudes. In Jiuzhaigou in winter, the temperature is generally between 10 degrees Celsius and MINUS 10 degrees Celsius, so it won't be too cold. Haizi presents three different seasonal landscapes due to the differences in altitude and underwater sediments. Generally speaking, Shuzhengqungou Haizi at an altitude of 2250 meters is still blue and green, with no signs of freezing; Rizegou Haizi at an altitude of 2660 meters presents a strange scenery of half ice and half water; At an altitude of 3 100 meters, the long sea is already a northland scenery wrapped in silver, and tourists can skate on it. Haizi is the pride and soul of Jiuzhaigou. The wanton water seems to be a sacred pool transformed from sapphire in Arabic mythology, in which snowflakes are like plum blossoms chasing water. Although snowflakes are floating, Haizi is still clear and transparent. With the different underwater sediments, they emit various colors such as blue, blue and green, and each color is quietly melted and dyed into several color levels: deep, shallow, transparent and clear. The glow of that color rippled in my heart, as if I were in a fairy tale world. When you arrive in Jiuzhaigou, you will find that the scene of "half ice and half water" is beyond your imagination. In ordinary imagination, the frozen part is crystal clear and the water is clear and green. But the color of Jiuzhaigou will definitely surprise you! On the crescent-shaped lake, the panda sea is half blue and half breast, like the eyes of a beautiful girl, charming and moving. Ice cubes with different thicknesses float on the blue Haizi in the sea of arrow bamboo, which makes Haizi change into various transitional colors such as dark blue, light green, navy blue, light purple and green. With the improvement of ecological environment protection in Jiuzhaigou, swans returned to Swan Lake in droves. Perhaps, this winter, the white swan met you unexpectedly. The highest and longest sea has been frozen, majestic and solemn, and the ice layer on the lake is as thick as five or six meters. Standing on the ice, the sun is particularly dazzling, and tiny ice particles are like a broken diamond in the sun, which is hard to stare at. The waterfalls in Jiuzhaigou also show ice and snow. Nuorilang Waterfall has become a huge natural art ice sculpture; Pearl beach waterfall and Shuzheng waterfall are sparkling and flowing like silk; Look at Panda Waterfall, like a dazzling world of ice crystals.
