"The heart has a clear connection" comes from the song "Singing at Night in the Prosperous Tang Dynasty".

Lyrics:

By God’s will, the emperor’s edict said:

I’ll be drunk with dragon paste wine, and I’ll take the luminous cup of grape wine

Give the ministers a gift to taste the food, and remember to add cinnamon when cooking sheep in a golden cauldron

Orchid wine shop lights and flowers shed tears, selling out the charm of a night with gold

The mist and rain gently scratch the back of the beauty, and appreciate the silk and bamboo Luo Yi is dancing

Yu Xuanji, why don’t you quickly perform a dance for me?

Chang'an willow catkins are flying, the harp is ringing, and passers-by are drunk

Upstream of the Hua Fang Lake, drink a cup to repay a cup

The water embroidery is beautiful with the needlework, the flat gold method, the painting Landscape

The poet's words fly, and the rouge sweeps across the eyebrows

Fireworks follow the flowing water, the night is cold, and those who are cold are drunk

At the current lantern festival, guess a pair of jacquard lantern riddles

Yangxian tea is floating in the water, the pipa is playing, and the jade flute is playing

Ding is offering sacrifices to Yi, and the bronze mirror is beautiful on the temples

The jade-like necklace between the ankles is painted by Feitian

The flowers in the courtyard are still hanging with dew

The general in the inn has returned from the battle

The war horses have not yet fallen asleep, and the beautiful lady is looking forward to the return of the moon

In the city gate of the prosperous Tang Dynasty, the wise are crazy and the idiots are sad

If a fool drinks a pot of wine, Yiliu will fall asleep early

General Pei Min dances with his sword and makes a rainbow in the hall. Moving the world

The magnificent scroll adds ink to the Chang'an song, and the wild cursive strokes are directed at Zhang Xu

Later, the ancients said again:

Last night's stars and last night's wind, painted To the east of Guitang on the west side of the building

There are no colorful phoenixes flying on the body, but there is a clear understanding in the heart

Chang'an willow catkins are flying, the harp is ringing, and passers-by are drunk

The upper reaches of Huafang Lake, Drink a cup to repay a cup

The water embroidery is beautiful, the gold method is flat, and the landscape is painted

The poet's pen is flying, and the rouge sweeps the eyebrows

Fireworks follow the flowing water, It's cold at night, and those who are cold are drunk

Today's lantern festival, people who carry painted lanterns will guess a pair

Yangxian tea floats on the water, the pipa plays, and the jade flute plays back

Ding Dance preparations for worshiping Yi, beautiful temples in the bronze mirror

The jade-like jewels between the ankles, painted with flying sky

The flowers in the courtyard are still hanging with dew

The general is already in the inn Returning from the battle

The war horses are not asleep yet, the beautiful lady is looking forward to the return of the moon

The tiles are flying, the carved glass is blowing in the wind

The prosperous Tang Dynasty raised long sails, A poem can make you drunk

The dragon's back is coiled in the imperial beam, with silver scales on it, and its momentum is brilliant

The silver moon is flying in the sky, leaving the west wing empty and I will not return
