It is surprising. China managed to successfully do the entire orbiter + lander + rover combo on Mars on the very first go with all systems being totally indigenous, new, and 100% untested and unproven ... until now.
I was expecting the lander part to be a failure and that wouldn't even be particularly bad. There are only four space agencies capable of putting such payloads into Mars orbit - China, US, Roscosmos, and ESA. To say nothing on landing which has only been done now by two nations. Great to hear for sure but definitely surprising.
