What about Weina 1C ?
Don't know if this was onboard but the three birds of this name are from three different producers and, I believe, the name itself is a delusion.

Maybe it is more confusing:
Micro-Nano-Star series built by Shanghai Engineering Center for Microsatellites: At least two satellites have been launched so far - Yijian (21.12.2016) and Weina-1A (25.01.2018)
Micro-Nano-Star series built by Beijing Minostar (MN10 platform): Two satellites launched as Weilai-1 (27.10.2018) and Weina-1 (07.12.2018). A third satellite built by Minostar was a 6U-Cubesat launched on 29.10.2018.
Very likely both series are independently of each other.
The launch of Weina-1 was announced shortly before launch here (https://www.lieyunwang.com/archives/449760) and confirmed here (http://www.fllo.cn/science/201812/39084.html). Consequently we have not 12 but 13 satellites on board Dec 7th launch.

It seems to me that the head of the CZ-2D at launch 2018-102 is much longer than at launch 2018-094.

It seems to me that among the objects in orbit at launch 2018-102, in addition to 12 satellites and the rocket stage, must be a large payload adapter.

Well, there was indeed a dual-payload adapter separated after Saudisat-5A but before Saudisat-5B.
On watching the TV feed at

I was able to read the planned separation sequence of the 12 satellites, as follows:

788.663   SaudiSat-5A
818.663   LadyBug 1
848.663   the adapter
878.663   SaudiSat-5B
918.663   Tianfu Guoxing 2
938.663   Tianfu Xinghe
963.663   TY/DF-1
983.663   LadyBug 5
1008.663   LadyBug 6
1028.663   LadyBug 7
1048.663   LadyBug 2
1068.663   LadyBug 3
1093.663   LadyBug 4

So one should map this triplet of Tianyi satellites on the other names such as Sagittarius-01, Douyu-666, Xijiang Jiaotong-01 and Xingshidai-2.

We know that Xijiang Jiantong-1 is TY3-01.

Sagittarius-1 is the name of the satellite plattform used for Douyu-666, Xijiang Jiaotong-01 and Xingshidai-2. The plattform was jointly developed by Tianyi and the Chegdu based Guoxing Aerospace company.Xingshidai-2 is TY/DF-1. But I have problems to map the remaining two Tianyi satellites to the Tianfu names. Liss, you write that you was able to read the separation sequence. Unfortunately I cannot read it from the video completely. Do you have some other images available?

I concur on this.

Thank you Liss, now I can see it. But it is the first time that I learn about Tianfu satellites as payloads of the Dec 7th launch. Tianfu was first mentioned in July 2017 as a remote sensing satellite project by the Chengdu municipality and to be built by Harbin HIT. First two satellites were planned for launch in 2020 (http://e.chengdu.cn/html/2017-07/30/content_602064.htm). But this does not correspond to the remaining two Tianyi satellites in question. Sorry but I am helpless $:-\$

some details about the chinese payloads from various internet sources:
LadyBug II 6U Elvis Radio Star for Elvis Radio
LadyBug III 6U Hua Mi Star / Hua Mi Xing (华米星) for Huami Technology (Huami Corporation): https://www.huami.com/
LadyBug IV 6U Panda Star? (a 'Panda Star' for tracking animals is mentioned in some pre flight reports, so maybe this is the one???)
LadyBug V 3U Lida Education Satellite (立可达教育卫星), seems to be identical to Youth (Junior) Star 2
LadyBug VI 3U Tmall International Star for Alibaba (Tmall International, ex Taobao)
LadyBug VII 3U RE: X-Star, related to Luhan Studio / chinese singer LuHan

TFSTAR =Douyu No. 666 (in cooperation with douyu.com aka The 'Fighting Fish' Company, a live-streaming provider; Wuhan Douyu Network Technology Co.)
Xinjiang Jiantong 1 =Xinjiang Traffic No. 01" (TY3-01) ...will serve in the construction of transportation infrastructure in Xinjiang Uygur autonomous region, as well as agriculture, security, tourism and environmental protection
TY/DF－1 by the Advanced Micro-Nano Research Joint Laboratory (Hunan Tian Yi Institute + Jiuquan Space Center)

The latter three are built on a common platform by ADA Space and operating in formation.
