Like Super Junior's "Sorry Sorry", there's not much of a melody going on here and
the four chords repeat throughout the whole song.
(It's not much to sing along with but oh well)

Gm (355333@1) Dm (xx0231@1) Cm (x3101x@1)  Eb (x43121@3)Gm: 446644
Dm: xx0231
Cm: x35543
Eb: x68886 (the Eb chord sounds better if you try and play only the 
strings)

Example of where to play chords (try playing with the actual music):

Gm (355333@1)   DmOh (xx0231@1)my super girl
Cm (x3101x@1)           EbNi (x43121@3)shi wo de baby girl


Beginning part (not 100% correct towards the end):

E|-36---------33365--3-35-35-333-10-8-3-633865-|
B|---36-4643-------36-4------------------------|
G|---------------------------------------------|
D|---------------------------------------------|
A|---------------------------------------------|
E|---------------------------------------------|

OR (same thing)

E|--6------------65-----5--5-----10-8---6--865-|
B|-8--6--6----888---68-8--8--888------8--88----|
G|---7--8-87-------7--8------------------------|
