Tian Yulan in Xiao Shede is a strong woman in the workplace, a person who pursues extreme self-esteem, and a very strict mother in her son Zi You.

Tian Yulan grew up in a poor family. After her parents divorced, she lived with her mother. Later, her mother married in disgrace in Nanjia, and her material conditions were greatly improved. However, other people in Nanjia, except Nanshu, have never had a good look at Tian Yulan's mother and daughter, especially Nanli, who secretly competes with her from time to time.

Tian Yulan is distressed that her mother has been unable to lift her head in front of Nanli, and it is difficult to avoid tit-for-tat. Therefore, she is strict with Ziyou, shaping Ziyou into a schoolmaster, which makes her gain enough attention in front of Nanli's family, but at first Nanli's family didn't care at all.

Tian Yulan thinks that her husband is an unprofessional and enterprising person, but fortunately, her husband's family is well-off, and she doesn't demand too much, but she is too proud to put all this pressure on Zi You. Perhaps in her eyes, only Ziyou's Excellence can prove how strong she is. Tian Yulan's education method is quite suffocating.
