I think when we eat out, we should order food in moderation and not order too much so as not to finish it; when we eat out and can't finish it, we should give up the traditional concept of packing, not thinking that packing is a loss of face, but packing away what we can't finish, so as not to cause waste; businessmen should put up slogans in the stores to tell the consumers that they should advocate thrift and that wastefulness is shameful.
