What you provide
Birth date, optional birth time, a normal place name and the choices that matter to your year. Confirm the resolved place before saving.
Free private preview
A useful BaZi preview starts with the right place and time.
You do not need to enter coordinates or an IANA timezone. MyTongShu resolves a normal place name on the server, shows the match and keeps the personal flow behind authentication.
What stays private
Birth details, chart facts, personal context and forecast results are never placed in public URLs, public HTML or analytics payloads.
What the preview shows
Three representative personalised days and an explanation of how the general date facts interact with your approved context. The paid product precomputes the full annual guide.
