I " This sentence came from San Mao's "Sahara Desert". The original text was: "It is better to rely on yourself than to rely on heaven and earth." You can't rely on anyone. You can only rely on yourself." This sentence expressed that when a person faced difficulties and challenges, the most important thing was to believe in himself and rely on his own strength to solve the problem. Even in times of difficulty, you need to actively seek help and support, but in the end, you still have to rely on yourself to solve the problem.
