The lunar soil had been to Hong Kong two years ago. It was put on public display at the Hong Kong Convention and Exhibition Center and received a warm response. It is believed the return of the lunar soil will further promote the development of scientific research in Hong Kong.

Packing in transparent containers, the dark-colored soil samples, in the form of powder and particles, totaling 822.6 mg, will provide scientists with research data to unveil the mystery of the moon.

In Hong Kong, there are not many academicians engaging in lunar science research. Qian joined the HKU after completing his doctorate degree at the China University of Geosciences (Wuhan) in December last year, and became the first person in the HKU specializing in the study of the moon.

Qian has long been engaged in the research of deep space exploration, lunar exploration and fields related. During his doctoral study, his team successfully applied for the first batch of lunar soil samples collected by Chang'e 5.
