The homeless man bought a flower with his only money and never forgot to carry it with him at all times. The blind girl's family situation is very poor. She only depends on her grandmother and sells flowers to support her family every day. The landlord's rent urging always makes their life very uneasy. With the help of the rich man, the homeless man gave the blind girl a lot of help. But in the blind girl's mind, this kind man should be a handsome, rich and powerful man. When the tramp faced the blind girl, all his kindness and concern came out. The blind girl has hope of regaining her sight. She can use the money to do surgery to treat her eyes. However, our homeless man is imprisoned. This level lasts for two years. The reunion of the two two years later is the most heart-warming scene in the entire film. The blind girl not only healed her eyes, but also opened a flower shop, and her life became rich. After being released from prison, the homeless man was so poor that even the newsboy with whom he had a good relationship made fun of him. When the tramp accidentally saw the blind girl, his eyes were fixed there, and then he showed an uncontrollable sense of relief and excitement. The uncomprehending girl thought he was a beggar, so she sent him away with a flower. We can notice that the tramp's eyes never leave the girl at this time. He seems to want to tell her that he is the one who gave her the money to treat her eyes, but he is too embarrassed to let her see the truth and be disappointed, so he does not speak. The girl put the flowers into his hands, and suddenly she felt that the texture of her hands was very familiar, and doubts filled her face. "Is that you?" the girl asked. "Yes." The homeless man replied shyly, "Can you see it?" The girl replied, "I can see it." After the brief dialogue, the film ended abruptly, leaving the audience with endless imagination. The reason why Chaplin did not show their subsequent situation was to preserve the best ending for the audience.
