Seen Chinese do (try) the same thing in plitwice national parks. There are only these small wooden paths leading down to the boats. Let’s put it this way: it’s rather unamused when someone two heads smaller than you and half your weight tries to force you into a lake/marshland. What is however amusing is simply stopping to move and watch them loose balance.
Boundaries like that don’t work, because, depending on the region, 5mio. could easily be your mom n pop shop or local doctor. Maybe we could tie it to certain tax indicators?
