Thanks for helping out! Here are the guidelines for suggesting characters:
The characters look similar to each other.
They are simplified or traditional hanzi.
Feel free to suggest more than two, as long as they all look very similar.
No pinyin, only the actual characters.
No commas, spaces or any other extra characters.
They don't already exist together in our database (do a quick search).
The entry will be moderated by a human, so it may take some time to be added to the site if it's accepted.
