Not sure where did he find it, but I found the two books in taobao, one is about 2500RMB(350USD), the other is 4500RMB(620USD), Chinese version only. As they said, it is "for studying the evolution of the moon, selecting the site for a future lunar research station and utilizing lunar resources". |
