This is unusual because typically for sliding wedge block cartridge charges are preferred because they are able to seal off the chamber which is a necessity as for a sliding wedge breech block. So it seems that China has figure out a way around this particular issue.
This ain't the 1930s. Sliding blocks and separate propellant charges (un-encased and burn fully) are not mutually exclusive. The Germans use them on PzH 2000.
