Fu Song'e

Murong Xi was said to have granted every wish from the sisters, and providing them with so much luxury that his small empire's resources were highly drained.

He also ordered the construction of Quguang Hai (曲光海; "Bent-Light Sea") and Qingliang Chi (清涼池; "Cool Pond") specifically for her.

[2] Murong Xi however preferred the younger sister Fu Xunying, whom he made the empress in January 404.

[4] In September 404, when Fu Song'e was taken ill, a man named Wang Rong (王榮) in the capital Longcheng (龍城, in modern Chaoyang, Liaoning) volunteered to treat her and promised cure.

However, Fu Song'e died soon after, and Murong Xi was so enraged that he had Wang Rong dismembered and his corpse burned in public.
