It's a custom to give red pocket with money inside from senior to the young during Chinese new year. This year I give this to teach them to know more about the world and possibly let them become a millionaire in the future. Things seem impossible may become true one day. However things that become true may turn out nothing later too. It is because social chaos, instability, economical crisis of a country may turn million of its currency just enough to buy a bread.
