Emperor Sechen of the Tatar state ascended the throne in the fourth month. On the nineteenth day of the fifth month, he established the Zhongtong reign era. Jia Sidao of the Song entered the court, serving as Right Grand Councilor concurrently Grand Preceptor to the Crown Prince. The northern emissary Hao Jing came to the Song to renew the alliance. Councilor Jia concealed his previous dealings and detained Hao Jing in Zhen Prefecture without sending him back. Another envoy came to Jinghu, and Councilor Jia again detained him at Chunkou in Hanyang, thereby bringing about the calamity of a broken alliance, which ultimately led to the fall of the state. In the tenth month, the Song appointed Qi, the son of the Emperor's younger brother Yurui, the Heir Prince of Rong, as Crown Prince, enfeoffing him as Prince of Zhong (Songjian).
