Later I found that the file was too large for 2,364 KB, and of course this ensures that the map is accurate, but we don't usually need that exact boundary, so it's necessary to narrow it down. Fortunately, there have been predecessors to do this work, really walnuts, posterity, here to express our thanks.Conversion method:1. Op
