What festival is depicted in "It's cool day and night like water, lying and watching morning glory and Vega"?

Today is Valentine's Day in China. The seventh day of the seventh lunar month is China's Valentine's Day, also known as Begging for Cleverness Festival, Seven Clever Days or Seven Sisters's birthday. Qixi, which began in the Han Dynasty, is a traditional cultural festival popular in China and other countries in the cultural circle of Chinese characters. According to legend, on the night of the seventh or sixth day of the seventh lunar month, women begged the Weaver girl for cleverness in the courtyard, so they called it "begging for cleverness".

Original poem:

Autumn night

Tang Dynasty: Du Mu

In the autumn night, candlelight reflected the screen, and Fan slapped the fireflies with his hand.

The stone steps at night are as cold as cold water, sitting and staring at the cowherd and the weaver girl.

Translation:

In the autumn night, candlelight reflects the painting screen and beats fireflies with a small fan.

The stone steps at night are as cold as cold water, sitting in the bedroom staring at the cowherd and the weaver girl.

Appreciate:

This poem is about the loneliness and bitterness of a frustrated girl's life. The first sentence is about autumn scenery, and the word "cold" is used, which implies the crisp atmosphere in autumn and shows the inner loneliness of the hero. Write two sentences to kill time and relieve depression by flapping fireflies. Three words: I can't sleep at night, waiting for good luck, taking the street as water to compare your love as ice. In the last sentence, I admire the Cowherd and the Weaver Girl to express my grief.
