Lin An.
Yongkang means similar to An, but since he is a man, he has his own pride. "Shuowen" says: "Lin is a big deer." It is used to describe outstanding people. Sima Xiangru's "Zixu Fu" of the Han Dynasty also said: "Shooting the Elk Foot Lin." In history, Yongkang was the reign name of Murong De, and he had a younger brother also named Murong Lin. Of course this is nonsense.
