That is not good advice imho. The CX PEK-HKG segment in J is regional business class. Nothing special and the flight times are not convenient. Also, by flying to Shanghai via Hong Kong, your out of pocket (for the HKG-PVG sector versus PEK-PVG) increases signficantly. Another option is to take the overnight express train between PEK and PVG.
