Gaofen-5 (https://space.skyrocket.de/doc_sdat/gf-5.htm)
When I checked on August 18 and 19, according to spaceflightfans.cn (http://www.spaceflightfans.cn/event/%e3%80%90tbd%e3%80%91%e9%95%bf%e5%be%81%e5%9b%9b%e5%8f%b7%e4%b8%99%e8%bf%90%e8%bd%bd%e7%81%ab%e7%ae%ad-%e2%80%a2-%e9%ab%98%e5%88%86%e4%ba%94%e5%8f%b702%e6%98%9f-%e2%80%a2-longmarch-4c-%e2%80%a2-gf-5-0?instance_id=5056), the launch of Gaofen-5 (02) will be on September 6, 2021, from Taiyuan LC-9.
(The same webpage also states Jiuquan LC-43/94 as the launch site, but the source material mentions the team exercise climbing a mountain on Army Day, August 1, to view the sunrise. That suggests Taiyuan.)
Gaofen-5 (01) launch thread (https://forum.nasaspaceflight.com/index.php?topic=39203.0); launch on May 8, 2018, 18:28 UTC.
Will Gaofen-5 (02) replace Gaofen-5 (01) in Sun-synchronous orbit, or take up a complementary position in SSO?

Some sites like that one were "temporarily" shut down by what would be the Chinese government.
-
From the little information that's available, it looks like this launch didn't happen.

From the little information that's available, it looks like this launch didn't happen.
Reviewing the Gaofen-05 01 launch forum, the confirmation was also late, the launch was expected at 18:20 UTC and was confirmed one hour later, but I think that in this case it is a delay.
-
The launch window is now over and there are no launch reports, which would indicate that the launch did not take place. Waiting for a report on the mission or a new NOTAM.
