The index is set by PM2.5 at 12.3 µg/m³ (sub-index 57).

These values come from the Copernicus atmospheric model as distributed by OpenWeather, sampled at the coordinates of Haikou. They are modelled concentrations on a grid, not readings from a monitoring station inside the town, so neighbouring localities in the same grid cell will show similar figures. Treat them as a regional indication rather than a measurement taken at your street.
