What is the result of learning to walk in Handan?

meaning

It should be affirmed to be diligent in learning from others, but we must proceed from our own reality, learn from the strengths of others and make up for our own shortcomings. If you despise yourself blindly, worship others blindly, and follow the trend mechanically, the result will inevitably be that you have not learned your strengths, but lost all of yourself.
