That's... probably not healthy to breathe. Or be within a hundred meters of.
Nitrogen Dioxide gas, correct? Produced from the Nitrogen Tetroxide left in the rocket?

China launches remote-sensing satellitehttp://news.xinhuanet.com/english/china/2014-08/09/c_133544286.htmJIUQUAN, Aug. 9 (Xinhua) -- China on Saturday sent a remote-sensing satellite into scheduled orbit.
The Yaogan XX satellite blasted off at 1:45 p.m. on the back of a Long March 4C carrier rocket from the Jiuquan Satellite Launch Center in the country's northwestern gobi desert, according to the center's statement.
The satellite will be used to conduct scientific experiments, carry out land surveys, monitor crop yields and aid in preventing and reducing natural disasters, the center said.
The launch marked the 190th mission for the nation's Long March rocket family.

Forgive me if this have been asked before, but why is the payload fairing shedding so much debris ?

Thermal insulation boards for the satellites - Jiuquan (and even so for Taiyuan) can get very cold in the night even in the summer! Also check out the original Ariane rockets for another rocket that sheds so much thermal insulation at launch.

Thanks for your answer! So I guess this means that they do not have active climate control, or that it is not powerful enough for the night temperatures.

The 3 lower lines on the display on the left indicate the expected times for the 3 satellites separations:
星(副星一)分离 Secondary satellite # 1 separation
星(主 星)分离 Primary satellite separation
星(副星二)分离 Secondary satellite # 2 separation

So that looks like T+1143 s for the primary sat sep, can't make out the ones for the secondary sat but maybe
1141 and 1145 s ?

I tend to read 1217s, 1345s and 1415s (no guarantee

Objects D and F have been switched: now D is the rocket body (CZ-4C 3rd stage) and F is labeled "CZ-4C debris"
