River breach at Baimaokou
The Yuan shi records a breach of the Yellow River at Baimaokou during the fifth month.
What this does and does not establish
元史/卷041, Wikisource revision 1814438. 河 denotes the Yellow River here. The complete entry supplies a month but no day, casualties or repair action; neighboring fourth- and sixth-month entries do not supply those details.

- Kind of record
- Placed in a year. A source places this in one year. It is listed under that year; no day precision is invented.
How it is dated
- Date reference
- 至正三年五月，day unspecified
- How we use it
- Year-level placement is limited to the dated source entry.
The date reference is this project’s reading of the source’s date. It may give an era name, a reign or a calendar in a normalised form rather than in the source’s own words; the dating notes say what the source prints.
Dating notes from the research record
Read yuan041.wikitext line 9 for the third-year heading and lines 15–19 for the fourth-, fifth- and sixth-month sequence. Read sinica-1342-12-31.html and sinica-1343-12-31.html headers and month cells: 1342-12-31 is 至正2年12月4日; 1343-12-31 is 至正3年12月14日. The fifth month falls wholly within Julian AD 1343. Original quotation begins at line 17, character 578.
File names and line numbers in these notes, and in the limits above, refer to the project’s retained copies of the cited sources. Names such as calendar_headers are the project’s calendar look-ups, and “the investigator” is the research step that prepared the record.
Sources and quoted text
Line and character numbers under “Location” refer to the project’s retained copy of the source. For database rows, “Edition” names the batch of rows that was fetched together.
