#钱包 shares a little trick for saving wallet private keys or mnemonic phrases. In the field of computer science, there is a concept called erasure coding, which involves splitting data into multiple redundant segments and storing them in a distributed manner. Even if some segments are lost or damaged, the original data can still be recovered. To give a simple example:

Mnemonic phrases can be divided into three parts: A, B, and C. AB is stored in one place, BC is stored in another place, and AC is stored in a third place. Only two of the three locations are needed to recover the original mnemonic phrase, so it doesn't matter if one is lost or leaked.

You can divide it this way as you like, splitting it into 4 parts or 5 parts is also fine.
