A launch timeline is shown in the 9ifly thread, but as I don't have an account there, the resolution is not readable.

http://www.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=14865&pid=700737

Looks like the deployment sequence was

CBERS 4A
Satellite adaptor
One small satellite
Three micro satellites
Four cubesats

See below. CZ-4B s/n Y44 was used for this launch.
I can translate the whole brochure at others' request.

Confirmation of launch success! Launch was at 3:22 UTC. Payloads were

CBERS 4A (China-Brazil Earth Resources Satellite)
ETRSS 1 (Ethiopian Remote Sensing Satellite)
Tianqin 1/CAS 6
Yuheng
Shuntian
Tianyan 01
Tianyan 02
Weilai 1R
FloripaSat

"Turn it around! Congratulate! China's successful launch of an arrow nine stars ( Weiwu) today at 11:22, China in Taiyuan Satellite Launch Center with the Long March IV B carrier rocket, the successful launch of the China-Pakistan Earth Resources Satellite 04A star. The satellite successfully entered the scheduled orbit, and the mission was a complete success! The China-Pakistan Earth Resources Satellite 04A is the sixth satellite developed by China and Brazil in cooperation. The mission also carried the launch of the Ethiopian microsatellite, Tianqin 1 technology test satellite, YuHeng satellite, Shuntian satellite, Tiantou 01 satellite, Tianqi 02 satellite, futural -1R satellite, Brazil 1U small satellite and other 8 satellites! "

According to the brochure Tianyan 01 = MN50-2 (=MN-50-01?), Tianyan 02 = MN6U-2 (=MN10-03?) and "Guozhi Henghao Nianjing 1" =Weilai-1R (replacement for the one lost in the October 2018 ZQ-1 flight? Possibly also = MN10-04?), all built by MinoSpace.

Yuheng and Shuntian seems to be names of 2 satellites from the National University of Defense Technology (NUDT) testing orbital router technologies.

The [ETRSS-1]satellite was designed by Chinese and Ethiopian engineers and the Chinese government paid about $6 million of the more than $7 million manufacturing costs

New commercial satellite launched in north China
XI'AN, Dec. 20 (Xinhua) -- A new commercial satellite was successfully launched from Taiyuan Satellite Launch Center in north China's Shanxi Province Friday.
The "BDSAGR-1" satellite has entered its scheduled orbit and is expected to provide accurate remote sensing data on crops in the river basins in north China and help modernize and digitalize China's agricultural industry.
The satellite belongs to the first phase of the "Guozhiheng Agricultural Remote Sensing Satellite Constellation" project jointly engineered by GasTianta and GZH-HNJ BDS AGR Co., Ltd.
Zeng Weigang, general manager of GasTianta, said the satellite was designed to operate in a sun-synchronous orbit with an orbit period of 96 minutes.
Zeng added that the project will eventually form a remote sensing satellite constellation consisting of 40 satellites covering the whole country.
"As a traditional agricultural country, there is still much room for improvement in the application of remote sensing satellites in China's agricultural field," said Zeng.
"We will continue to deepen the R&D and marketing of commercial aerospace technology and explore the application of remote sensing satellite technology in areas such as agricultural resources investigation, crop monitoring, disaster monitoring and food safety traceability," he added.

This satellite seems to be Weilai 1R, which other name is Guozhi Henghao Nianjing.


EDIT : adding bold.

A launch timeline is shown in the 9ifly thread, but as I don't have an account there, the resolution is not readable.

See below. CZ-4B s/n Y44 was used for this launch.
I can translate the whole brochure at others' request.

What is the first word/phrase on step 13 of the launch sequence? (ideally pasting the Kanji, I can't copy from the image to google translate).
I assume it refers to the two NUDT satellites but I can't make it out.

I'm having trouble matching the brochure to the sats. It looks like the sequence is:

T+798  CBERS 4A sep
T+833  Upper adapter sep
T+868  medium-large payload Tianqin 1 sep
T+905  medium-small payloads NUDT sats?  and Tianyan-02 sep
T+947  small payloads Ethiopia, Floripa, Tianyan-01, and Guozhi.. (Weilai1R) sep

But this doesn't seem consistent with the rest of the discussion about the payloads which should
be 
medium size:   ETRSS, Guozhi/Weilai-1R, Yizheng/Tianyan-01
medium-small: Tianqin-1
small :      Floripa, Tianyan-02
unknown but probably small:  NUDT sats Yuheng and Shuntian

Clarification sought :-)

That's correct. "Orbital Router Demonstration Twin Satellites" is the name given to them two here for NUDT's satellites.

Your satellite separation is correct. I won't trust the size of the satellite models used other than the number of satellites....  ;)
