The real name of Mile Mile Seafood may be known only by Mile Mile Seafood, but others don't. The online guess is:

* Zhang Haiyang, because "ocean" and "seafood" are homophonic.

* Chen Hai, because "Chen Hai" and "Morning Sea" are homonyms, and the word "morning" is also included in the name of the seafood.

These are just netizens' guesses, and there is no conclusive evidence.
