Although Luo Bin-wang wrote about Wu Zhuo, Luo Bin-wang was a talented poet, and he had a great talent for politics, so Wu Zetian valued Luo Bin-wang's talent, so she reused him. In the early life of Wu Zetian's accession to the throne, many subjects, such as Luo Bingwang, had great opinions about a woman being the monarch. In ancient times, women's status was far inferior to that of men, and people's thoughts were generally patriarchal, so when Wu Zetian ascended the throne, it attracted many criticisms, among which Luo Bingwang was one of those people.
But among these people who question Wu Zetian, their purposes are not the same. Some people are only for their own interests, while others are considering the whole world. The purpose of Luo Bingwang's doing this is the latter. Wu Zetian is very familiar with this force that questioned him. After consolidating her power, she began to eliminate these officials who accused him only for her own interests. At that time, many ministers were exiled without officials. Apart from the exiled ministers, Wu Zetian also felt bad feelings for other people in this force, secretly reducing the power of these officials and not reusing them.
But for Luo Bingwang, who is politically talented, Wu Zetian forgave him for disrespecting himself before. More power was given to Luo Bingwang, because Wu Zetian thought that Luo Bingwang could make good use of these powers to benefit the world, and when Luo Bingwang carried out some reforms that were beneficial to the prosperity of the country, he had more power in his hands, and the process would be smoother. Such talents can't be alienated because of their narrowness. In order to make the country strong, Wu Zetian put down her prejudice against Luo Bingwang.
In addition, Wu Zetian has just ascended the throne, and her inner circle is not mature enough. At this time, she desperately needs some excellent talents for her own use. Luo Bingwang is a good candidate, and it also shows his attitude to the talented people in the world. As long as he is talented and can serve the officials and the people, he can go to serve the people under the authority of today's queen. This is the reason why Wu Zetian later reused Luo Bing Wang, although he wrote a letter about Wu Bang in the early stage.
