Thanks, but my main point is that those amendments and changes
to Boon Lay Bus Services (mainly feeders and services that served
the industrial area like 79, 192, 193, etc.) was very confusing in
the 1990s and 2000s. The services has major route changes which I
couldn't find anywhere, that's why I need someone's help to find
out the routes of the continuously amended services.
