China's top aerospace scientists said on Wednesday that more young people and institutions in the Hong Kong Special Administrative Region are welcome to join in exploring the mysteries of space.

They said China needs talent from all places, including Hong Kong, and such collaboration will offer a broader stage for them to give play to their strengths.

The invitation was made by Qi Faren, chief designer of China's Shenzhou spacecraft, and Hu Hao, chief designer of China's phase-three lunar exploration program, during separate lectures at Hong Kong Polytechnic University and the University of Hong Kong, respectively.

The lectures were the first two public events of an exchange visit made by a high-level national aerospace delegation, including Qi and Hu, from Tuesday to Saturday in Hong Kong.
