The singer is from Taiwan - 羅志祥
Ghost laughter can be heard .... at the 58/59th second.
The background sound got the faint and short "he he he he"..(ghost laughter) ~ You need to listen carefully..tune up your speaker volume if need to..ok
Is this a recording fault/error ? ...or a real ghost fan behind the scene~ wow..who knows
Anyway , i like this nice song ~ yeah !
News report ... the "hehehe" sound can hear clearly from here
