In her speech, Lam said she believes Hong Kong people have a special affinity for the Chang'e lunar exploration project. It was not because of her name "yuet-ngor", which reminds people of Chang'e, a Chinese goddess of the moon in the folk tale, but the city's participation in the project.

The Hong Kong Polytechnic University designed a system to collect and pack samples on lunar surface for the Chang'e 5 mission in 2020 and also for the upcoming Chang-e 6 mission. It helped the probe of Chang'e 5 mission to collect lunar samples of up to two kilograms and bring them back to the Earth.
