Dudes, so they finally released a finished version of the music video  xD which has atrocious rainbow-colored English lyrics xD But you can check some funny remarks and a quickie English translations from Beijing Cream.
You can also check a slightly better quality version of the video on YinYueTai — but still not crisp enough to be able to read the tiny English caption xD
I’m rather surprised I only know a little over +30 names xD and a little more of the faces, including a brief apperance by Ajia  and Li Yu Gang (李玉刚) whom… you know, you can’t totally tell from just the audio. I’m also rather SHOCKED that I didn’t get Song Zuying from early on the song but her later bit xD
Judging from the song alone (okay, and a bit of the video), Sa Dingding did great. This was her Beijing Welcomes You [MV] 5-sec Bibi moment for me. xD The song is no Beijing Welcomes You, though. And I love some of Chang Shilei’s stuff. His 2008 Niu China album was my favorite that year, and he does produce some great songs like I Would Say to Them (对他说我愿意)  or HIGH歌 — OMG, are you watching The Voice of China [clip] ? xD
Also, the video is pretty cheap. Walking down a shelves of book of… what I supposed is the Beijing library or something. xD And also the people that weren’t in Beijing and obviously couldn’t be flown to shoot for the video because of budget. I’m looking at you guys, Eason and Aaron~~~ and Kelly Chen xD
