Taiwan Identity

Road Sign Math goes international! This time we visit Taiwan for the very first time, thanks to Darren Hodges. Messr. Hodges runs a signspotters website. He brings us this sign from Tainan. I'd be happy to comment on the contents and directions of the sign, but I have no idea what it says.



This math is the basic of the identity proof. Any number times 1 is itself, even 1.

$$1 \times 1 = 1$$

This sign is from Tianan, Taiwan.
