Perhaps you have some answers. Answers that are not acceptable: I don’t know, or google it.

• Question: Is there such a thing as Chinese morse code? How does it work?

• Question: Is all braille the same, or does Chinese use a different system?

• Question: Similar to the question above, how about sign language?

• Question: It is easy to tell someone in English how to spell something, you just tell them the letters. How does it work    in Chinese? If you didn’t have the chance to show them, do you just describe how the squiggly lines look?

These things need to be answered. Thank you.
