Oh, another idiot who believes in use of PPT's. You really are a joke.

Typical of useless laowai who have been in China for way too long.

Useless Chinese teachers use PPT's, it all they know how to do.

They can't conduct a class without using a PPT.

I even lambasted and humiliated a few Chinese teachers at a university for using PPT's.
every day.

Nobody should listen to you [edited]
