that is wrong.

I haven't seen any text book mention the term 钱学森弹道 or Tsien's trajectory or anything like that. As many Chinese netter mistakenly attributed skip reentry to Hsue-Shen Tsien or Qian Xuesen. The first person proposed this idea was Eugen Sanger. His idea was to use skip reentry to increase range and overcome heat. However his idea was wrong. Qian on the other hand did the work guidance control for glide reentry which was proposed by engineers in RAND coorperation. I read Qian's paper on that subject, and he actually made it possible for Germini, Apollo and later Space shuttle reentry.

Btw, I don't think I will ever response to conspiracy theorists who know shit about aeronautics and astronautics. It is wasting bandwidth to response to you.
