How many lines are there in the typhoon path of the applet on WeChat?

Due to the influence of the shape, position and intensity of subtropical high, the typhoon's moving path is not uniform and becomes diverse. According to the query of China Meteorological Network, the typhoon path refers to the path that runs after the typhoon is formed. It can be roughly divided into three categories: westward migration, landing and turning. There are many reasons for the typhoon path, mainly because the typhoon is affected by complex atmospheric environment and other factors in the process of atmospheric movement. So the applet on WeChat has several typhoon paths.
