I try to translate, maybe it is not original meaning because never I have thought my homesickness in English.
The homesickness is an endless line in my heart:
It’s a family line: as a son, worrying about my parents
It’s a time line: in my middle age, recalling my childhood
It’s a distance line: living in the South Hemisphere, missing my hometown far away
It’s a connecting line: no matter where being, my heart tied to China
It’s a line in my dreams, often bringing me home to be with my family and taking me back to my childhood.
