Or only YG-30? Why?
Capture from SciNews's excellent video (this user must have some great sources). Shows the three satellites as 07, 08 and 09.
it is quite possible that they work together but all we know from the State media and the forums in China is that YG-30 operates with the YG-30 Groups and that we may see additional launches for this Constellation in 2018 to further expand coverage in this multi inclination constellation.
