I finally got watch the full program. Regarding the serials, as off 2nd Sep:
3P10 and 3P09 are in sub-assembly (fwd fuselage taking shape. Notice in 2nd pic the "cockpit walls" are almost 20 cm thick - an A4 page is resting on them - this lends further credence to the fuel tank theory since its more than the critique of them being only a couple of cms thick):

(cockpit in inverted position visible in the far side of picture, the A4 sheet rests where the popular pipes will later be installed, 5 brownie points if you can spot the additional hardpoint):

(3P09 in foreground and 3P10 in background)
View attachment 777862
(3P09 wings, also labelled as 7th aircraft - implying 2 prototypes/ examples were built in China - this serial convention is similar to that observed with Bs)

3P07 and 3P08 fuselage sections not seen in any shot.
3P07 wing jiggs:

3P05 and 3P06 most likely (mid fuselage section visible on the rightside likely goes with 3P09 almost complete front section):

Looks like we are on schedule to have a good many ready by year end, maybe even the 12 originally planned for this year i.e. upto 3P014
