I'm teaching myself and my students to use this method to enhance the memorization of the meaning and the pronunciation. Unfortunately, it still lacks of remembering the tone. For examples:
(1) 兔 --> that's a rabbit, too
(2) 没 --> I don't have holiday in May.
(3) 肉 --> A piece of meat is rowing a boat.
(4) 呼吸 --> Who can see me breathing?

      It could be fun and overwhelming. The key is not to overuse it and can't be use for every character. Otherwise, it would be time and energy consuming.
       Have you tried it in your language learning?
      Thank you for bringing up this insightful topic and sharing the link.

@Terecia!

Thanks! Yeah, it was a misunderstanding. I wondered how you taught them using a Memory Palace, not mnemonics in general. I'm really good with mnemonics and in theory I know how a memory palace works but it still seems so difficult for me to create one, because I somehow can't believe that I'll be able to visualise it. The mnemonics are just sentences for me. I don't have a very vivid picture in my mind. When I close my eyes and try to picture walking through my house, I see nothing. That's my problem.

Thanks a lot for all the comments. It seems that mnemonics in general are widely used, but so far nobody who actually uses the memory palace has commented. The difference between free floating mnemonics and a memory palace is that the words/phrases/information that one wants to memorise are assigned specific places in the memory palace. With this technique you can not only memorise information but also in a specific order.

Yes, like Sherlock and the Mentalist. :)

Thank you Miriam!
