What do you mean, it's never been today?

"Never put up with today's chicken" means that you can put up with today's eggs. "Vertical chicken" means vertical egg, which is the custom of vernal equinox.

"Today, the chicken is not standing, and the good people in Sichuan put paper kites." From Sima Xiangru's Vernal Equinox, the original text: The sun and the moon are in the sky, and the mysterious birds are not afraid of peach blossoms. Since then, the chicken has stood up, and the lover in Sichuan has put a kite. It means: at the vernal equinox, the peach blossoms are in early bloom, and the swallows fly back from the south regardless of the chill. You can lay eggs today. Someone is flying a kite by the river. It tells two important customs of the vernal equinox. "Vertical chicken" is vertical egg. It is said that at the vernal equinox, picking up a smooth egg can easily stand it on the table. "Chicken" is homophonic with "auspiciousness", and the vernal equinox "vertical egg" is intended to keep spring and breed auspiciousness. With this explanation, we can feel how splendid the vernal equinox is in spring, and people need to "stand upright" to keep it.
