In terms of the Chinese market, they like to invest in LLLL.coms with no A, E, I, O, U, V.
There are nice comparable sales for your domain with taox.com for $1,500, daox.com for $15,000, and taoc.com for $4,900.
Price it anywhere from mid $xxx to mid $xxxx depending on how long you wish to hold.
Best of luck!
