I noticed another wall-hanging scroll in Shenmue II, so thought I would add it here to the scrolls talked about on this thread earlier.
It can be seen in one of the shops on Dragon Street in Kowloon (thanks to James Reiner for his no-clip video of Dragon St
here).
The scrolls on the left and right walls, "道可道非常道", is one that also hangs in the Hazuki Dojo, and is the first line of the Classic Chinese text Tao Te Ching. It can be translated as "The Way that can be told of is not an unvarying way". The translation given in the game is "Principles cannot be expressed only by words".
This shop also has a different scroll on the back wall, "名可名也 非恒名也". This is the second line of the Tao Te Ching and means "The names that can be told of are not unvarying names".
