Actually is wasn't written by Johnny Thunders at all. Most of it was written by Dee Dee Ramone, another 2 verses was written by Richard Hell who was, of course, also in the Heartbreakers and also a junkie.
1) Hey man, you got any Chinese rocks?
2) A: Hey man, you heard that song, 'Chinese Rock'?
B: You mean the Ramones one? I like the Heartbreakers version better.
B: It sounds dirtier. I like that.
