The assistant minister was a high-ranking official in the ancient Chinese official system, but it was not the highest ranking official. The official position of assistant minister in the Tang Dynasty and Ming Dynasty was the third rank, equivalent to the current minister and deputy minister. The assistant minister was the deputy chief of the six departments, responsible for assisting the minister in handling affairs. The minister was the highest officer of each department, while the assistant minister was the minister's deputy. Therefore, although the assistant minister had a higher status in the official system, he was not the highest ranking official.
In the Tang Dynasty, a marquis was a title of nobility, not an official position. Marquis was the title of nobility in ancient China, representing a status that exceeded the first rank. Marquis was usually only awarded to the royal family and a few meritorious officials. It was a kind of reward and honor. During the Tang Dynasty, the title of Marquis was a noble title, and it had no direct connection with the actual rank of the official position. Therefore, Marquis was not a specific official position, but a title of reward and honor.
The Assistant Minister of Revenue and Count Sinan of the Qing Kingdom was an official position. Fan Jian had held this position in the last few years of the Qing Dynasty. He was the assistant minister of the Ministry of Revenue, and he also held the title of Count Sinan. Count Sinan was an honorable title, representing honor and glory. Although this title did not have any real power, in the Qing Emperor's heart, Fan Jian's status was very high and he had important positions and power. Fan Jian was in charge of the country's financial statistics and other work. At the same time, he commanded the Emperor's personal guards, the Tiger Guards, and was responsible for protecting the Qing Emperor's safety. Even though Fan Jian's official position was not the highest, his status and influence at the Qing Emperor's side could not be ignored. Thus, the Assistant Minister of Revenue and Count Sinan was a high-ranking official position that represented Fan Jian's status and prestige in the Qing Kingdom.
