Kassey Lee breaks down how these domains might be used.
eName just reported some four-letter domains sold recently from its marketplace. As you can see, there is a large variation in the prices, which makes domain investing very challenging. I have added my own suggestions as to what these acronym domains can mean in Chinese.
KGZJ.com was sold for 29,999 yuan (about $4,500). KGZJ may be Pinyin phrases such as Kuai Gou Zhi Jia (快购之家=home of speedy purchase), Kao Gu Zhuan Jia (考古专家=archaeology expert), and Ku Gong Zuo Jian (酷工作间=cool working space).
LYQC.com was sold for 2800 yuan ($420). LYQC may be Lu You Qi Cai (旅游七彩=colorful tour), Le Yu Qian Cai (乐于钱财=take pleasure in money and wealth), and Ling Yang Qing Chun (羚羊青春=youthful as antelope).
ZPBF.com was sold for 2,788 yuan ($420). ZPBF may be Zhen Pin Bu Fa (真品不乏=no lack of genuine products), Zhao Pin Bu Fan (招聘不凡=recruit the extraordinary), and Zhao Pian Bin Fen (照片缤纷=vast and various photos).
ORQP.com was sold for 2,080 yuan ($310). ORQP may be Ou Ran Qi Pao (偶然旗袍=incidentally wearing Qipao), Ou Rui Qi Pai (鸥锐气派=an imposing manner like a sharp gull), and Ou Ri Qi Pei (欧日汽配=auto parts from Europe and Japan).
Four-letter domains are used in corporate China, for example, MGTV.com (Mango TV) and CCTV.com (China Central Television) in the 2019 Top 100 Chinese Internet Companies Report.
