The meaning of BTS's crow

A proverb that the revolution originated in South Korea. The literal translation of the proverb is "A crow flies with a stork, and its wings must be broken." In other words, don't bite the bullet and take an egg. Bulletproof claims to be a crow, and sings that the stork's legs and feet have become stronger, so the deeper meaning is that being beaten will only make bulletproof stronger. The above is taken from Netease Cloud Music Review Area.
