Over the years I have aggregated a set of resources which I have found useful to inform at least a superficial understanding of Chinese cyber and are used to feed /r/blueteamsec and the Blue Purple Pulse respectively. Below is the summary, if you have any others please email them over and/or add to the comments.
It goes without saying that to read most of these you will need to leverage various translation solutions be it within Browser or otherwise.
High Quality Meta Sources
A number of high quality Chinese meta sources that are highly recommended for checking daily.
360 CERT Daily
360 CERT’s daily security briefing comprised of links. Includes a lot of Western content but will also surface useful regional content as well.
Note: No content is added during the weekend of Chinese public holidays.
Sec.today
Doesn’t just pull in solely Chinese sourced information, but does include some by virtue of being Chinese and is good for surfacing high quality technical content.
Sec.Today cross-references multiple public data sources to build a centralized hub for all things infosec.
Cybersecurity information flow
As with the previous one above doesn’t just pull in solely Chinese sourced information, but does include some by virtue of being Chinese.
A clean information flow push tool, biased towards every bit of the security circle, to discover high-quality content for security researchers every day.
Safety Hourglass-Scientific Research Data Exchange Platform
Provides a rich source of Chinese language cyber research both high and low level in nature.

Code Audit
As the name implies provides a focus on code and web security specifically. Excellent source for staying appraised of the web techniques, capabilities and research focus out of China.
"Code Audit" is a professional, cutting-edge, and original Web code security and audit discussion community. We focus on sharing original code security knowledge, vulnerability mining methods, and eliminating link transfers, data reprinting, and other behaviors.
Wider Chinese Native
A number of Chinese native sources which vary in their quality and focus but all are worth reviewing semi regularly. The volume of some is hard to appreciate until you try and consume it all.
Threat Intelligence
Various open source threat intelligence reporting is available from Chinese sources which give insight into their unique perspective.
Security Star Chart Platform
A threat intelligence database from a firm in China which provides good summary reporting generally monthly in Chinese as well as other infrequent posting.

News Sites and Super Aggregators
Numerous high volume sources and communities exist in China which provide rich sources of information and insight yet a tremendous amount of volume.
