There were several reasons why the Qing Emperor had Fan Xian come to Jingdou. First of all, the Qing Emperor was Fan Xian's father. He wanted to see Fan Xian's ability with his own eyes and hoped to use Fan Xian's existence to temper Crown Prince Li Chengqian. Secondly, Fan Xian's mother, Ye Qingmei, had a business in Jingdou and died there. The key to a box that she had left Fan Xian was also in Jingdou. This was another reason Fan Xian had come to Jingdou. In addition, the Qing Emperor also wanted to test whether Crown Prince Li Chengqian and the Deputy Commander of the Imperial Guards, Gong Dian, would rebel when worshipping the Qing Temple. The Qing Emperor's actions caused people to speculate. Some people thought he was using Fan Xian, while others thought he truly had the heart of a father. In short, the Qing Emperor had Fan Xian come to the capital for many reasons, including testing Fan Xian's ability, finding the chest Fan Xian's mother had left behind, and testing the loyalty of the Crown Prince and Gong Dian.

There were several reasons why the Qing Emperor wanted Fan Xian to return to the capital. First, the Qing Emperor wanted to test Chen Pingping and Fan Jian's loyalty to him. Chen Pingping and Fan Jian were good friends of Ye Qingmei and had special feelings for her. The Qing Emperor was worried that they would discover the secret of Ye Qingmei's death and use it as an excuse to rebel. By letting Fan Xian return to the capital, the Qing Emperor tried to see Chen Pingping and Fan Jian's attitude toward Fan Xian and use this to judge whether they could be trusted. Secondly, the Qing Emperor wanted Fan Xian to marry Lin Wan 'er, take charge of the palace treasury, and take back the property that belonged to him. The Qing Emperor deliberately arranged for Fan Xian to meet Lin Wan 'er to test Fan Xian's character and ability. The Qing Emperor hoped to use this marriage to control the Qing Kingdom's finances. Lastly, the Qing Emperor was Fan Xian's biological father. He did not want his illegitimate child to stay in Danzhou for long. He wanted him to come to Jingdou to observe and train his abilities. It was also possible that he wanted to train Crown Prince Li Chengqian. In summary, the Qing Emperor had Fan Xian return to the capital to test Chen Pingping and Fan Jian's loyalty. He wanted Fan Xian to marry Lin Wan 'er and take charge of the palace treasury, as well as to observe and hone Fan Xian's abilities.
