When Mark first arrived in Thailand, he saw an old man selling something cheap in the street of Chiang Mai. The old man was one of the poor people in Chiang Mai and there was no difference from beggars (乞丐). Most of them were some lonely old people. Their life had no support.

Mark was a kind man, so he gave some changes to him without thinking. The old man told him to pick something he liked. Mark didn’t choose anything and left.
