Literally, I leave home alone to be a guest in other places, especially when the festival comes, I miss my loved ones.
Brief analysis: the first sentence uses a word "unique" and two words "different", which is enough. My thoughts about my loved ones and my feelings about my lonely situation are all condensed in the word "independence". "Being a stranger in a foreign land" only refers to being a guest in another country, but the artistic effect caused by the word "different" is much stronger than that caused by the general description of being a guest in another country. "Foreign land" and "stranger" are the simple and true expressions of this feeling. A stranger's homesickness naturally exists on weekdays, but sometimes it doesn't necessarily show up, but once it encounters some kind of catalyst-the most common one is "festival"-it is easy to explode and even uncontrollable. This is the so-called "I miss my relatives twice during the festive season". Festivals are often a time for family reunion, and many fond memories of hometown scenery are often associated, so it is natural to "miss your family more during festivals".
