China News Service, Los Angeles1October 3 (Reporter Jia) According to Sing Tao Daily, it is well known that Qian Xuesen, the "father of Chinese missiles", was detained and obstructed when he returned to China. However, three of his students were implicated in his return to China and were detained in Japan for three months, but little was known. China scholars living in the United States now recall that they spent time in prison with their mentors without any regrets. Mr. Luo, who is engaged in research work at the University of California, Irvine, in his eighties this year, recalled that he had just received his doctorate from Qian Xuesen at California Institute of Technology, and Qian Xuesen's being prevented from returning to China had a great impact on 12 international students in China. He, postdoctoral Shen Shanjiong and physicist Yi decided to go back to Japan together. When they left the United States on August 3, 1950,/kloc-0, they found that some Americans recognized them and were mistaken by their friends for not having passed the visa in Hong Kong.
