Thank you for the post!
This spiritual beginning of the Chinese people is all new to me (although not surprising). I had never run across Shang Di, the one supreme God. (Will look into more.)
Question: how did the Chinese lose their spiritual roots? For comparison, although the Hebrew tribes were chosen by God to be a model for humanity, some of their leadership (starting with Solomon) slid into apostasy, leading to the exile, etc. Apparently the lust for power was too tempting for some of the early Chinese tribal leaders, and once the first emperor seized absolute power, there was no turning back.
As God works with the few Christian leaders in China today, we can hope for a slow but steady return to a spiritual-based leadership (but not likely in our lifetimes).
Blessings.
