Hi Joe,

Happy to see engagement in evolving wallet systems. Unfortunately, BIP39 was devised precisely to avoid users picking their own phrases, as that is extremely insecure and cannot be expected to generate sufficient entropy to protect coins. Humans are inherently bad sources of randomness - all mnemonic systems need to be randomly generated.

If you are interested in continuing development in this area, you could try devising a system that generates readable sentences as mnemonics. I'm not sure if this would work in Chinese, but in English I feel it would be possible.
