There is a kind of flower called fireworks; There is a kind of smile, which is called "Fireworks Laughter". This fireworks, however bright, can only be seen in an instant, burning and struggling, and scattered all over the city. The past is gone, and the life is like this. Passing through the hustle and bustle of a lifetime gives the fleeting time a glimpse of prosperity. One thought is persistent, one thought is fireworks, one thought is extinguished, and everything goes its own way. Fireworks, loneliness. Fireworks laugh, laugh at the whole city, beautiful years, spent a floating life.
