These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

"Funny Aneurysm" Moment: The book was originally written for Helu, the ruler of the Kingdom of Wu. About fifty or so years after Sun Tzu's death, Wu was completely destroyed and absorbed by the Kingdom of Yue.
