Once feathers become wings, take them to the branches of the yard.

Once the wings are full, lead the swallows to the branches in the yard.

Liu Sao and Bai Juyi can be seen in strict poems.

There is Shuang Yan on the beam, a male and a female. Between two rafters, a nest gave birth to Si Er.

Si Er is a long day and night, and the voice of asking for food is diligent. Caterpillar is not easy to catch, and the yellow mouth has no heyday.

Paws are eager for us, but they are not tired. For a moment, I was afraid of hunger in my nest.

After 30 days of hard work, mom's skinny chicken is getting fatter and fatter. Muttering, brushing sweaters one by one.

Once the wings are formed, lead them to the branch of the court. Raise your wings and fly in the wind without looking back.

Men and women sing in the air, but their voices don't return. But to enter the empty nest and sing all night.

Yan Yan, don't be sad, but think about yourself. Imagine yourself as a young day, flying high and carrying your mother.

At that time, my parents thought that I should know today.

The full text means:

A pair of swallows are flying on the beam.

Busy with mud, nesting in the rafters,

Four little swallows were born (soon).

It is not easy to have four children,

Growing swallows have been begging for food.

Insects are not easy to catch,

Swallows' hungry mouths are never full.

Although Qin Yan is very tired,

But the swallow is still worried about not having enough to eat, so he doesn't feel tired and continues to feed.

Back and forth several times in the blink of an eye,

Still worried about starving the swallow, afraid to relax.

It is difficult to feed swallows for about a month.

Swallows grow up, but their relatives are getting thinner and thinner.

Where is the mother bird? I mumbled to teach swallows,

Comb their feathers one by one,

When swallows are full of wings, take them to the branches in the yard.

As soon as the swallow spreads its wings and flies, it never looks back.

Suddenly, it flew everywhere with the wind.

A pair of mother birds are flying in the air, calling the swallow back to its nest.

However, the song was over, but the swallow did not fly back.

The mother bird returns to the empty nest,

Crying all night.

Swallow, swallow, (referring to the mother bird, the poet speaks to the mother bird below)

You shouldn't be so sad,

You should think back to what you have done before,

Think about how your parents took care of you when you were a child.

Think about when your wings fly away from your parents.

At that time, my parents were very concerned about you.

You should know by now!
