What does Ctrip theme tour "deep photography" mean?

It is a theme tour mode launched by Ctrip, with photography as the theme. The depth photography group, which provides photography guidance, will go to some beautiful scenic spots for photography. In-depth photography groups pay more attention to showing the charm of photography during the tour than ordinary free travel and pure tour groups. Seda Daocheng, which has been reported for 8 days before, is worthy of praise for its outdoor tripartite confrontation.
