You should ask them first. Where can you do it right away? However, You Ran also asked Confucius this question, and Confucius replied: Of course, it should be implemented immediately. Gong Xihua saw the same question and gave different answers. He couldn't figure it out, so he asked Confucius. Confucius said, Ran Qiu should be brave, but he should be cautious when traveling.

It is Confucius' exhortation to his disciples.
