I have to say Taiwanese are very honest.
A man went to railway company for returning the ticket price which owed few decades ago on TV.
When he was a student he didn’t have enough money to pay tickets always. He always try to avoid to be checked by controler.
Few decades pass, he still remembered it. He brought full money to return railway company that he should pay few decades ago.
And, It is not a single case. There is many people like him to return money of railway company.
