Korean artists give themselves names.

I just answered the same question you asked, haha.

Jin Jifan-a member of ——SHINNE.

Jin Qifan/Jin Jifan-super junior member

Jin Fan-The actor plays Su Yizheng, the "Flower Man".

Korean names are very popular, such as Chang, Min, Jun, Ji, Shang, Hao, Yun and so on. Words with ordinary sounds are generally used in translation. After all, they are transliteration.
