CHINESE NEW YEAR DECORATIONS CAN BE TAKEN DOWN AFTER THE 15TH DAY OF LUNAR NEW YEAR
Caller: When should we take down the Chinese New Year decorations like the character 福 (‘fu’ which means blessings or fortune) or the Chinese paper-cuttings?
Master Jun Hong Lu: You may take them down after the 15th day of Lunar New Year. Yesterday happened to be the 15th day, you may do so now.
