Great news for people who don't want to wait until October 1st to catch a glimpse of Sound of the Desert. Tencent, one of the largest web portal in China, procured the rights to broadcast a "sneak peek" version of the series starting September 28, 2014 (12:00 a.m.) Beijing time, which means the first chapter is already available for preview. "Sneak peek" version of the drama is Tencent's cut
For those who are unable to navigate Chinese websites, I will post episode links to the Tencent version of Sound of the Desert here. Just revisit this post tomorrow for the release of next episode.
TIP: Tencent has regional restriction on its video contents. For many viewers outside of mainland China, please install/add the extension Unlock Youku on your web browser. I have no issues viewing restricted videos on Chinese web portal after adding the extension on my Google Chrome web browser.
EDIT: I misread the announcement on Tencent. They are not releasing a 20-minute cut for each episode, but a 20-minute cut for the next several days until the official broadcast date. I think the Tencent's Sneak Peek version is the rumored 66-minute trailer Tang Ren released during the press conference in Shanghai.
