Extended data:

The embryo outlines the blue-and-white brush strokes that turn from thick to light.

The peony depicted on the bottle is like your first makeup.

I know Ran Ran sandalwood through the window.

The pen on the rice paper is half here.

Glaze color rendering the charm of female figure is hidden.

You smile like a bud.

Your beauty is drifting away.

Go where I can't go

The sky is blue, I am waiting for you.

Smoke from the stove floated across the river thousands of miles away.

Carved calligraphy at the bottom of the bottle imitates the elegance of the previous dynasty.

Think of it as the foreshadowing of meeting you.

The sky is blue, I am waiting for you.

The moonlight was salvaged, dizzy.

For example, blue and white porcelain passed down from generation to generation.

There's a smile in your eyes

Koi fish, with white flowers and blue color, jumped to the bottom of the bowl.

I miss you when I copy my signature.

The secret you hid in the kiln for thousands of years.

Very delicate, like an embroidery needle landing.

Outside the fence, bananas cause showers and knockers cause patina.

I passed by that small town in the south of the Yangtze River and made you angry.

In splash-ink landscape painting

You are hidden in the depths of ink.

The sky is blue, I am waiting for you.

Smoke from the stove floated across the river thousands of miles away.

Carved calligraphy at the bottom of the bottle imitates the elegance of the previous dynasty.

Think of it as the foreshadowing of meeting you.

The sky is blue, I am waiting for you.

The moonlight was salvaged, dizzy.

For example, blue and white porcelain passed down from generation to generation.

There's a smile in your eyes

The sky is blue, I am waiting for you.

Smoke from the stove floated across the river thousands of miles away.

Carved calligraphy at the bottom of the bottle imitates the elegance of the previous dynasty.

Think of it as the foreshadowing of meeting you.

The sky is blue, I am waiting for you.
