Note too that the lander is released before MOI.

yet in the following sequence you can see it released at apoapsis in Mars orbit (Steven Pietrobon's 3rd screen capture)

I guess I read the diagram as show the ultimate orbit, but could have misread it.

this has just appeared on the Journal of Deep Space Exploration:

Analysis of Key Technologies for Unmanned Mars Sample Return Mission
http://jdse.bit.edu.cn/sktcxbcn/ch/reader/view_abstract.aspx?file_no=20160203&flag=1

Quote
Unmanned Mars sample return mission is of great significance to obtain scientific results and improve engineering ability. The mission period is longer and technical risk is higher compared with several foreign Mars landing and roving missions. The top-level system design is determined by the mission flight mode. The rendezvous capture and sample transfer process should be completed near the Mars orbit. Therefore,two probes with different functions are required:one is used to perform Mars capture, sample storage and Mars-Earth transfer,the other to complete EDL process,Mars  surface ascent and sample delivery. Such key issues as EDL mode,Mars ascent vehicle,Mars orbit rendezvous and capture,sample transfer,earth entry vehicle,system scales,rocket selection,etc. are analyzed in this paper. The main technical difficulty and solution approaches are discussed.

The Chinese certainly don't mess about! Going straight for an orbiter/lander/rover in their second attempt. If this is a success, I wouldn't be surprised if their next mission is a Mars sample return. The lander capsule is also more head-light shaped, then the more traditional saucer shape used in the past.

Here's the engine nozzle, showing the spiral tube wall construction. The video also mentioned they are building a new hydrolox engine with three times the thrust of YF-77.

2 minutes ago from Weibo weibo.com
[Scheduled! # China ’s first Mars exploration mission named Tianwenyihao #] April 24 is the fifth “Chinese Space Day”, the name of China ’s first Mars exploration mission and the mission logo will be launched at the 2020 China Space Day Announced on. The Chinese planetary exploration mission was named "Tianwen" series, the first Mars exploration mission was named "Tianwen-1", and the subsequent planetary missions were numbered sequentially. According to reports, the name is derived from Qu Yuan ’s long poem "Questions of Heaven", which expresses the tenacity and perseverance of the Chinese nation in the pursuit of truth, and embodies the cultural inheritance of the exploration of nature and cosmic space. Endless. The mission logo symbolizing "Lan Xing Jiutian" shows the image of the unique letter "C", which brings together the multiple meanings of China's planetary exploration (China), international cooperation spirit (Cooperation), and the ability of deep space exploration into space (C3). Demonstrated the concept and attitude of China's open space cooperation. (People's Daily Client)

Yup, and the name will be used for future Chinese planetary exploration missions as well.

https://twitter.com/Cosmic_Penguin/status/1253514691365597186

It means "To Ask The Heavens" and is from the name of a long poem dated back to the 3rd Century BC:

The Mars rover will get a name later through a separate naming competition.

So the Mars mission is 天问 and the China Space Station Experimental module 1 is 问天. Kind of strange.
This message reflects my personal opinion based on open sources of information.

So the Mars mission is 天问 and the China Space Station Experimental module 1 is 问天. Kind of strange.

Indeed, in Chinese both would have approximately the same meaning....  :-\
