An afterword about the tailor’s craftsmanship

Sewing needles carefully.

The tailor’s ruler is the measure of others, not of yourself. A tailor's iron - it burns people. The tailor's head - seriously, blocking the needle, swinging the needle. The tailor girl is so ruthless, and her needles are ruthless.

Afterword: The tailor's ruler - only measuring others means to only pay attention to the shortcomings of others, but not to pay attention to one's own problems.
