"Being alone in a foreign land is a stranger", the first sentence uses the word "alone", and the word "different" describes the poet's lonely feelings and thoughts for his loved ones. A "stranger" is a guest in a foreign land. The word "different" shows that the poet strongly feels that he is a duckweed floating in a foreign country, leaving his hometown where he has lived for many years, with no relatives around him and a local accent in his ear, and that everything is strange and unaccustomed. "Foreign land" and "stranger" are the simple and true expressions of this feeling. Therefore, it is also conceivable that in normal times, poets always miss their hometown and their loved ones. On the Double Ninth Festival, poets always think of the day of family reunion. Among them, "every hour" refers to every festival and "missing my loved ones twice", which shows that the poet is full of nostalgia for his hometown. In addition, the same is true of "thinking twice about your relatives during the festive season"
