Like your filial towards parents and always there to take care of family needs improving their lifestyle. However, as old people, need patience to slowly educate them. In Feng Shui geomancy, we dun keep broken bowls and plates as invite bad luck. Its good to explain to them let them decide to invite bad luck to keep old and broken utensils. Than, they will be more willing to discard. Explain to them that It can affect family luck, children or generations. So, its their decision. The food storage really too much. If expire to throw, than very sinful. Use wastage creating sinful act to educate them. Educate them look around , other starves to death without food. Too much storage, waste space and need time to upkeep. Buying excess is as good as throwing away money. Take all the excess food, use calculator to convert into cash. Let them see and feel how much money they will be throwing away if expired. Hope these methods can help to change their mindset.
