YAN发香迷
[yan fā xiāng mí]
This nickname 'Yan Perfume Enthusiast' could denote a fanatical lover or connoisseur of fragrances (possibly incense). Yan means perfume and fa-xiang (in pinyin for 发香) together usually indicates incense. It's a niche, aesthetic-focused alias for someone interested in this particular aspect of Chinese culture which holds that incense can enhance spiritual practice and create ambience.
