Although they have the same path, the derived public key and private key are asymmetric, for example:

xprivate_key：m/44'/0'/0'/0/0
xpublic_key：m/44'/0'/0'/0/0

Due to the hardening derivation, the expected symmetric results cannot be obtained, even though they were initially symmetric.

Their paths are equal, and the public and private keys are also symmetric, for example:

xprivate_key：m/0/0
xpublic_key：m/0/0
