This answer to Has an astronaut ever seen another object in LEO pass by that wasn't mission-related? says:
The encounter happened at longer distances ($\sim47\;km$) and the Shenzhou-7 is smaller than the Tiangong-2 ($9.25\;m$) so the view was not so spectacular from the ISS. Apparently the EVA of Zhai Zhigang (the first Chinese spacewalk in history) happened at the same time as they approached the ISS. We should ask him if he took a moment to see the ISS. (emphasis added)
while the EVA was taking place on Sept. 27, 2008, the SZ-7 spaceship came fairly close (within 47 km) of the International Space Station (ISS)
I don't know how to ask Zhai Zhigang but I do know how to ask a question in Space SE.
Question: Is it at all known if CNSA astronaut Zhai Zhigang see the ISS during an EVA? Would it at least have been possible and/or likely?
