Not much we leave behind is lasting. I mean look back in history and tell me the amount of things compared to what existed then, still do today. China has an ancient history so I would suspect there are various things that go back a long ways. It is highly likely that some which have survived the ravages of time are not exactly what the original owner would have picked to be the thing to be associated with his/her name.
All the rest is like footprints on the sand; those things in your life today and often the majority won't survive even to your old age.
So one child and that's about it.
