The red light needs to cross the road, which means that you may not be able to do a lot of things, but you must think well, not just be prepared for danger in times of peace, but have the spirit of daring to fight. This sentence comes from an article by Wang Lu, an invisible author. The original text reads: Zhu Yifa's signature is "The red light must be forced to cross, and the road must cross". This sentence made me conclude that he was a wonderful work before I met him.
