Aside from some ancient tracks and certain "worn-down" circuits, the drainage capabilities of most normal tracks in F1 are not weak; otherwise, how could they meet the standards of international event grade tracks?
Even after more than a decade, China still only has the East Sea track up to standard, with tracks like Haizhu and Shudu in the application process, as the assessment standards are actually not low.
The reason for various issues with F1 tracks stems from the long sixty-year history of the event, where many tracks are not solely about racing; they also have historical and cultural ties, and sometimes even political significance.
For instance, around 2010, F1 expanded greatly to better increase its influence globally, significantly increasing the number of races in Asia.
