"Uncle, I have tried my best" is not a movie line, but an online buzzword. Used to show that you did your best for something, but the final result was not satisfactory. The buzzword originated from funny videos or jokes, and it quickly became popular on the Internet because of its humorous expression. In life, when people encounter setbacks or difficulties, they will use this sentence to express that they have tried their best. Although unwilling, but also can only face the reality. It more embodies an optimistic attitude towards failure and a determination to actively seek solutions to problems.
