Extended information:

Li Bai's "Quiet Night Thoughts" was created in a Yangzhou hotel on September 15, the 14th year of Kaiyuan (726) by Emperor Xuanzong of the Tang Dynasty, when Li Bai was 26 years old. At the same time and in the same place, there was also a song called "Traveler's Feelings on an Autumn Evening". On a night with few stars, the poet looked up at the bright moon in the sky. Feeling homesick, he wrote this famous poem "Thoughts on a Quiet Night" that has been passed down through the ages and is well-known at home and abroad.

The first two sentences describe the poet's momentary illusion in the specific environment of visiting a foreign country. Anyone visiting a foreign country will have this feeling: being busy during the day can dilute the sorrow of separation, but in the dead of night, homesickness will inevitably arise in the heart. This is especially true on moonlit nights, especially autumn nights when the moon is like frost.

The word "suspect" in "Suspect is frost on the ground" vividly expresses that the poet woke up from sleep and mistook the cold moonlight shining in front of the bed for thick frost covering the ground. The word "frost" is used better. It not only describes the brightness of the moonlight, but also expresses the coldness of the season. It also highlights the loneliness and desolation of the poet wandering in a foreign country.
