A documentary chronicling the coming of age of a young chinese man.

Workers, peasants, soldiers, students and merchants were five groups of Chinese society in the 1950s, after the so-called elimination of the exploited class. Borrowing this concept, the umbrella is taken as the clue to rediscover changes in various social classes after the economic reform, and to analyze the social problems in China. Workers making umbrellas, merchants selling umbrellas, students looking for jobs in the rain. Umbrella is used as a metaphor that can be seen everywhere. As the raindrop, what we see is sometimes clear, sometimes untraceable.
