"Being a stranger alone in a foreign land" begins with the poet's loneliness in a foreign land. The poet used one word "independence" and two words "difference" in this short sentence, which shows that the poet has a strong feeling of living in a different place. The lonelier he is outside, the more he misses his relatives in his hometown.
In the feudal society at that time, the traffic was blocked, people lived a self-sufficient life, and there was little communication between regions, so people in different places had great differences in customs, living habits, language and so on. Therefore, the poet left his hometown where he had lived for many years and naturally felt strange and lonely. The poet described his life in a foreign land flatly, but it contained his simple thoughts and feelings.
If the feeling of homesickness on weekdays may not be so strong, then the poet "misses his relatives twice during the festive season." "Festival" is a time for relatives to get together and talk and laugh.
Now, the poet lives alone in a different place, and in the festival representing reunion, he can't help but think of people and things in his hometown, mountains and rivers and other good memories of the poet when he was in his hometown. All kinds of memories lead to the poet's infinite homesickness, and the more he thinks about it, the more he misses it, so that it is out of control. This sentence is very natural and simple, such as eloquence, and it also writes a lot of real feelings of wandering outside, which is very representative.
