What does one-stop funeral service mean? Is it true that you don't have to work hard for the aftermath after spending money?

Funeral service units integrating funeral parlours and cemeteries have established a complete service chain of "contact-pick-up-storage-wake-funeral-burial-sacrifice sweeping" according to the service process.

But I still want to participate, not because I spent money.

What I know is that the immediate family members must be present at banquets (until burial), wreaths (purchased by relatives), quilts (brought by relatives), wakes, mourning (or spending money to cry), cremation (sending bodies and taking ashes) all the way to burial.
