That long numeric domain name might actually mean something.
When you look at the domain 7708801314520 .com, what do you see? I see the “Kiss you, hug you, and love you forever” romantic expression. Quite impressive, right?
A number has no intrinsic meaning. However, you can attach a Chinese meaning to it through a process called rhyming. This technique may be unique to the Chinese language, as I have not found such ability in the English language.
For example, the number “1” rhymes with (sounds like) 一 (one), 依 (depend on), 医 (medical), and many more. Similarly, “3” rhymes with 商 (business), 山 (mountain), 生 (alive), and many more. Putting “1” and “3” together, you get many combinations of the Chinese characters. Some may work and some may not, but one that does work is 一生 (all my life).
Now, look at the number 7708801314520 again. It can be seen as having the following parts.
|770||亲亲你||Qin Qin Ni||Kiss you|
|880||抱抱你||Bao Bao Ni||Hug you|
|1314||一生一世||Yi Sheng Yi Shi||Forever|
|520||我爱你||Wo Ai Ni||I love you|
7708801314520 has now become “Kiss you, hug you, and love you forever.” Incidentally, the domain was registered in 2005 but is not developed.
Long numeric domains may be meaningful, but are they useful? One issue is that the meaning is lost when you use the domain outside China. Also, long numeric domains (beyond 4N) are rarely used in corporate China (although I think there may be opportunities to use them in advertising). As I see it, long numeric domains are mostly for trading between investors.
