Because Xie Fangde was a loyal minister who was patriotic and loyal to the monarch, even if the Southern Song Dynasty perished, Xie Fangde was unwilling to betray his original country. Later, due to Yuan Di's persecution, Xie Fangde died of hunger strike. Xie Fangde loved reading since he was a child, and his personality was very generous. At the same time, he hated evil. At the time of the imperial examination, Xie Fangde, who could have been ranked first, offended some officials in the imperial court because of some remarks in the article. Therefore, after the list came out, Xie Fangde was relegated to the second class.

Then, Xie Fangde abandoned his official position and retaken the exam. This time, he was appointed as a professor in Jianningfu. In the later period, because the Mongolian army invaded the Southern Song Dynasty, Xie Fangde was promoted by the imperial court to a cabinet of the Ministry of Ritual Forces, which was mainly responsible for recruiting militia and raising military salaries. In order for the country to have enough strength against Mongolia, Xie Fangde took the initiative to sell the property and give it to the country.

It was not until Xie Fangde was appointed as the examiner that Xie Fangde was demoted to Yangxin County, Hubei Province, because he disagreed with the capitulators and was suppressed by court officials. After three years, the pardoned Xie Fangde returned to his hometown. During the recruitment in his hometown, Xie Fangde volunteered to join the army and became a soldier in the Mongolian army.

After Mongolia changed its name to Yuan, Mongolia invaded the Southern Song Dynasty in order to achieve reunification. At this time, Xie Fangde was re-used by the imperial court. Even if there was unfair treatment, Xie Fangde still led the people to stubbornly resist the menacing Yuan Army. After successive defeats, a large number of officials in the Southern Song Dynasty fled in succession. At this time, Xie Fangde still stubbornly resisted with the army, but finally failed.

Xie Fangde, who was pursued, went back to his hometown to teach in order to escape the pursuit of Yuan soldiers. After the reunification of the Yuan Dynasty, a large number of officials in the Southern Song Dynasty were ensnared by the Yuan Dynasty, and Xie Fangde was finally found because of his great fame.

Although Yuan Di's solicitation was rejected, Xie Fangde did not escape from Yuan Di in the end. On the way of forcing Xie Fangde to become an official, Xie Fangde finally died of hunger strike.
