What does it mean to take a chicken feather as an arrow?

Chicken feathers are as light as catkins, and wooden arrows are as heavy as pine cones. Chicken feathers come from animals, while wooden arrows come from plants. Chicken feathers are thrown silently, and wooden arrows fall powerfully. The flight state of chicken feathers is a curve, which has been floating for a long time. The flying state of the wooden arrow is a straight line, and the running speed is as fast as lightning. Chicken feathers can't hurt people, but wooden arrows can hit you with one blow and seal your throat with one arrow. That's why the ancients made a big fuss about it, acting as military orders, threatening the three armed forces and plotting evil.
