At noon we reached the border between China and Russia in the northwest of Erguna, across the Erguna River as a border river, and looked across Russia. Then we headed to the downtown Erguna. After many days of rain, the sky finally began to clear, the white clouds exposed the blue sky, the flat grassland extended to the distance, the washed grassland was more green, and the flocks of cattle and sheep were eating grass leisurely... The grassland scenery that was not enough! The multi-ethnic settlement of Erguna City is the birthplace of Mongolian ethnic groups, with more than 7,000 Russian and Chinese-Russian descendants. So at noon we chose a Russian farmhouse, carrying a welcome brand of dumpling model, antlers chandelier, and distinctive food, and we enjoyed a pure Russian lunch. After eating a Russian lunch, we continued to head to Hailar. The sky was clearer in the afternoon, sometimes the sun showed its face from the cracks of the clouds, projecting a cloud shadow on the grassland. The wind was blowing and the clouds were moving on the grassland, forming a bright spot on the grassland, and the grassland finally showed us its bright side. Tomorrow is going to return, and you have to leave the beautiful grassland far away. Your eyes can't help but see more of the beauty of this grassland, the green and vast grassland, the herdsmen of cattle and sheep, the shepherds who ride horses or motorcycles, everything is so beautiful, so unforgettable!
