"Tin Mah" not "Dai Mah"

Having shown photos of "Tin Mah", I'd like to show the Chinese characters of the name "Tin Mah", which are in the 1st photo.

By mere coincidence, the Chinese term for Tin Mah is very similar to that of cannabis which is shown in the 2nd photo. The only difference is that there's an additional horizontal stroke in the word "Tin".

The sound is similar too. Cannabis is "Dai Mah".

Please do not mix up the two. If you go about in Hong Kong saying that you possess "Dai Mah", you're getting yourself into trouble! Don't say I didn't warn you.
