One of the most expensive domain names sold in 2012 was giftbasket.com. It went for $350,000, according to DN Journal, a domain name industry news magazine.
Yu said he has enjoyed some success from trading domain names. One consisted of three digits and ended with ".cn", a "short number" category favored by Yu.
"Short number" domain names are usually favored by digital device makers or telecommunication operators. Some numbers are regarded as auspicious in certain cultures and trades and consequently are especially popular among enterprise owners.
Yu said he bought the name for more than 10,000 yuan and sold it for more than 100,000 yuan - a yield of 10 times the cost.
Yu declined to detail the precise amount he bought and sold the name for because he regards it as commercial privacy.
Another domain name was short and in pinyin. It (fuyun) sounds like "floating cloud" in Chinese, he said.
"I bought it without realizing it could be regarded as something precious, because when I first saw this name I just felt it created a beautiful image. I did not expect that someday it would turn into a symbol for cloud computing," said Yu.
"Sometimes it takes a bit of luck to be profitable in this trade," said Yu.
Zhang Zihao, an information consultant with a Shanghai-based technology firm, said investors also need to think about the challenges that increasing coding applications set on domain name trading.
