According to the information provided, in the TV series "Changfeng Crossing", Fan Yu's ascension to the throne process does not seem to be simple, involving many political struggles and the growth and transformation of characters.
First of all, Fan Yu's father, Fan Xuan, became emperor with the support of the Empress Dowager and Lhotse Shang. But Fan Xuan realized that as a father, he lacked the education of his son Fan Yu, especially in Fan Yu's growth environment and education. Therefore, in order to ensure that his son can succeed to the throne smoothly, he began a series of political arrangements.
In the context of the initial determination of the country, while Fan Xuan was busy with government affairs, he also focused on cultivating Gu Jiusi, an emerging political force, and named him the head of the household department, intending to maintain the dynasty through Gu Jiusi and use his talents to deal with national affairs.
But Fan Yu was dissatisfied with his father's reuse of Gu Jiusi, and coupled with Luo Zishang's provocation, he became suspicious and dissatisfied with Gu Jiusi. As Fan Xuan's health deteriorated, he formed a cabinet before his death, and set up a mechanism for Fan Yu's succession so that Fan Yu could ascend the throne smoothly.
However, with Fan Xuan's death, Fan Yu, under the further influence of Lhotse Shang, began his reign. After he ascended the throne, due to the instigation of Lhotse Shang, he began to be a loyal minister and named Xifeng a concubine. In this process, Lhotse Shang played a key negative role, taking advantage of Fan Yu's weaknesses, resulting in Fan Yu's behavior and decision-making being greatly affected during his reign.
In this narrative, we can see the complexity of the court struggle and the multifaceted character of the characters, but also reflect the profound impact of power on the individual, whether it is the owner or the successor.
