What is the reason for the extreme high temperature climate in South China this year?

The subtropical high in the western Pacific has a wide range and strong intensity, with the ridge extending westward and the ridge extending northward. The South Asian high is north-east and the tropical cyclone is south, with early plum blossom and short rainy season, which leads to long-term regional high temperature weather in the middle and lower reaches of the Yangtze River in southern China.
