Episode 16 recap: Hua Zhi discovered that Gu Yan Xi belongs to the Qi Su Division.

Xia Jin E asked Xia Ming to secretly manage the Hua family's accounts to prevent unnecessary worries among the other family members. Hua Zhi asked Hua Ling to become a female teacher and offered a valuable repaired painting as a gift. Hua Ling agreed. In order to prevent the children from becoming craftsmen, Hua Zhi moved the classroom to the training ground and invited experts from various industries to give lectures. Gu Yan Xi took the lead and shared knowledge from the northern region.

The topic of the northern region weighed heavily on everyone's mood, but Gu Yan Xi emphasized its advantages and uplifted spirits. The diverse courses broadened the horizons of the Hua family's children, and Gu Yan Xi also arranged morning runs to improve their mental state. Hua Xian took his son back to his mother's home but left in a hurry without visiting his mother. Hua Ling taught a class for the first time, covering profound content and adopting a strict attitude, which frightened the students. Fortunately, Zheng Zhi warned from outside the window, stopping her.

Shao Yao was deceived by Shen Huan's classmates and believed that Shen Huan was seriously ill. Fortunately, Shen Huan arrived in time to save him. Afterwards, Shen Huan learned that it was Shao Yao who had caused his facial allergy by drugging him. When Ying Chun arrived, Shen Huan chose to silently leave.

Ying Chun didn't recognize Shen Huan, but Shao Yao called him "Shen Er," which angered Gu Yan Xi. After Gu Yan Xi learned of Shen Huan's whereabouts, he personally went to find him. At the same time, Chen Qing learned that Madame Wei was going to Shanhua Temple today, so Gu Yan Xi asked him to follow her.

Chen Qing took the opportunity to take away a secret letter, which Lin Wan discovered and asked Hua Zhi to copy it. While Hua Zhi was copying the letter, Gu Yan Xi suddenly appeared and cornered her. However, Hua Zhi was not afraid and aimed a sleeve arrow at Gu Yan Xi, forcing him to let her go.

Gu Yan Xi told Hua Zhi the purpose of his visit, and Hua Zhi handed over the secret letter. Gu Yan Xi discovered that the content of the letter was unrelated to any serious matter. It only discussed the deep friendship between Lin Wan and the Empress Dowager, expressing their feelings for each other. Gu Yan Xi wanted to take away these letters to prove the innocence of the Hua family. Hua Zhi spent the whole night copying the letters.

The next day, Gu Yan Xi left with the letters. Gu Chengtao reminded Gu Yan Xi not to be sentimental. Gu Yan Xi stated that this trip was not only for the secret letters but also to find clues about the big fire that happened years ago.
