Why is the Xisha Islands very hot, but the coast of Heilongjiang is covered with snow?

Because our country is so vast, we have different looks at the same time. According to relevant public information, China's territory spans a wide latitude from north to south, most of which is located in the middle latitude area, belonging to the north temperate zone, and a few areas in the south are located in the tropical zone south of the Tropic of Cancer, with no frigid zone, high latitude in the north and low latitude in the south. In winter, the height of the sun at noon in the north is small, the days are short, the solar radiation heat is less, and the temperature is low. In winter, the sun is higher in the south at noon and longer in the daytime, so more solar radiation heat is obtained and the temperature is higher. The north is close to the source of the winter wind, which has a great influence on the temperature. The winter wind intensifies the cold in the north. The south is far away from the source of the winter wind and is blocked by many mountains, especially the east-west mountains. When it reaches the south, it is weak or can no longer affect the south, and the temperature in the south is high. Therefore, in winter, the Xisha Islands are hot, the trees are lush, and the coast of Heilongjiang is covered with ice and snow. The reason for this difference is the large latitude between north and south in China.
