Chinese Wikipedia lists 57 units in service, with 11 commissioned thus far in 2020. The origin of the discrepancy between Chinese Wikipedia's 11 units and the "9 units so far in 2020" headlines is unclear, though several units are listed simply as having been commissioned in "2020", i.e. no specific date. Possibly the status of these units is disputed or no commissioning ceremony was observed/reported?
Yes, 101 has a unique bow. The other 052D is likely 120 "Cheng Du", as shown in this video (2:00):The last shot looks like it was taken from the bow of the Nanchang.
