How to write in a tin foil red bag

Tin foil red envelopes can be used to describe the heart. The words "May the spirit of heaven be dedicated to so-and-so relatives" can be written on the tin paper bag for worshipping relatives, wishing so-and-so relatives a pleasant journey, a blessed afterlife and a peaceful soul. There are not many fixed formats, so it is a folk taboo not to write the names of living people on them as much as possible.
