Don't be fooled by your brother in Nanjing at night (the local drivers in Nanjing are very poor). They are lying when they take you to KTV! It is run by the underworld. Hit people without giving money. It is normal that there are many such taxi drivers in every city. Not that there are flies or mice in every line. Therefore, we should believe that there are still many good people in this world, but we should strengthen our judgment, not be greedy and cheap, and not have crooked ideas. We have to understand that pies don't fall from the sky for no reason, even if they fall, they won't hit you.
