Where does China have the most thunderstorms? Please introduce it in detail

Hainan Island and Leizhou Peninsula are the places with the most thunderstorms in my country, with an average of 100 thunderstorm days every year. The thunder period is from March to October every year, of which May to July is the low-altitude thunder period. During this period, lightning often harms people and animals. July to October is the period of medium- and high-altitude thunder, which is often accompanied by storms or heavy rains. Hainan Island has the peak rainfall period from May to June every year (mainly summer typhoon rain), and the peak rainfall period from August to October is the typhoon rain period. The rainfall in the two peak rainfall periods accounts for more than 70% of the total annual rainfall, with an average rainfall of about 2,000 mm. The annual rainfall in the eastern mountainous areas of Qiongzhong County and the western Wanning County is as high as about 3,000 mm. The highest rainfall in Qiongzhong County in the year is 5525.5 mm, the highest rainfall on the island. According to records, there are an average of 130 thunderstorm days in Suxian County on Hainan Island a year, and the maximum number of thunderstorm days in a month is 27 days. The Leizhou Peninsula in western Guangdong Province was called Leizhou in the eighth year of Zhenguan (634) in the Tang Dynasty. In the early days of Tianbao, Leizhou was renamed Haikang County, and in the early Qianyuan Dynasty, it was renamed Leizhou. In the Yuan Dynasty, it was called Leizhou Road and belonged to Huguang Province. It is clearly called Leizhou Prefecture and belongs to the Chief Envoy of Guangdong. In the Qing Dynasty, it was still Leizhou Prefecture and belonged to Guangdong Province. Leizhou got its name because of the many mines in the place (see "Taiping Huanyu Ji" quoted from "Touhuang Lu"). The Leizhou Peninsula is famous as the second minefield in the world, where lightning and thunder are frequent and severe. It is said that people who have lived in Leizhou for generations like lightning and thunder. It turns out that this place was once a dry area with "thousands of miles of red land". People described it as "three days without rain will cause a minor drought, and seven days without rain will cause a severe drought." Thunder can bring wind and rain and moisten crops, so people are happy when they hear thunder.
