What is the Tong Shu?
The Tong Shu (通書, also written 通勝), also called the Chinese Almanac or Huang Li, is a calendar of traditional date markers. For each day it gives Day Officers, an overall day verdict, entries for everyday activities and reference hours. People use it as one planning input next to practical evidence, not as a prediction.
How to read a public date
- Start with the date, reference time zone and method version.
- Read the Day Pillar and Day Officer as general context.
- Compare suitable and avoid activity markers with real constraints.
- Use the reference hours as a prompt, not as a guarantee.

Personal suitability
A private guide can compare approved personal inputs with the same general facts. That result remains authenticated and non-indexable.
Next step
Read a date, then explore the assumptions before deciding whether a private preview is useful.
Frequently asked questions
Is the Tong Shu a prediction?
No. It is a traditional planning reference. It describes how a date is marked in the almanac; it does not predict what will happen or guarantee an outcome.
Is the Tong Shu the same as the Chinese almanac?
They belong to the same family of date references. MyTongShu uses Tong Shu for the date-based almanac; Chinese Almanac and Huang Li are other names used in different contexts.
Can the Tong Shu tell me the best day?
It can show how a date is marked for a specific activity, such as signing a contract or moving house. It cannot rank every day for your life, and practical constraints should come first.
How is the Tong Shu different from BaZi?
The Tong Shu reads the date itself, the same for everyone. BaZi, also called Four Pillars, reads a birth chart. MyTongShu keeps the General date reference and your Personal comparison separate.
