What month is the rainy season in Zunyi, Guizhou? Help the gods.

Due to the northward summer monsoon (southwest airflow), the water vapor swept from the Bay of Bengal and the Indian Ocean increased greatly, and Zunyi entered the rainy season around April 16, with frequent moderate to heavy rains. From May to June, the summer monsoon moved to the Yangtze River basin and met with the northerly airflow, resulting in rainy weather in the Yangtze River basin. Zunyi City is located in the upper reaches of the Yangtze River, which also produces heavy rainfall and frequent rainy weather. The summer monsoon continues to strengthen, and the southwest airflow continues to push north. Zunyi city is controlled by the pure southwest monsoon, and the rainy weather begins to end, and it enters sunny, high temperature and dry weather with little rain. In mid-September, the summer monsoon gradually weakened and retreated southward, and the winter monsoon gradually strengthened southward, and Zunyi began to experience continuous autumn rain. In the future, when the winter wind basically controls Zunyi, it turns cloudy and gloomy.
