Not the same person, since the rower was born April 1994. However I do agree with both your logic that Zhu Yangzhu is needed to command re-entry.My bet is on the male newbie, Zhang Zhiyuan (张志远). According to English Wikipedia, there is apparently a Chinese athlete (rowing/crew) with the same name (in both English and Chinese) who won Gold at the 2019 Ottensheim World Championships in the Lightweight Quad Sculling event (also Silver at the 2018 Asian Games); if this is the same person, then it'd be natural to have him perform this one-year endurance event since we know that, at least to those of us who had suffered in this sport in any capacity during our youth, rowing is one of the premier endurance sporting events on par with ultra-marathons and cycling.
Good on Zhang Zhiyuan then! Only 9 people have stayed in orbit for more than a year at once, and also gets to meet the first HK astronaut and Pakistan astronaut on same tirip!
Since this is essentially a test for deep space exploration, I assume we will shortly have a 365-day mission for the female arm of the trial as well.
