graphic design salary in Shanghai or Beijing

all of my firends backgrouned in graphic design are not paid well in shanghai.middle leveld designers 4000–10000RMB after tax and only 3000 for 1-2years expirenced desiners.
that’s the payment for local desiners. if u can bring the theam something fresh, you can ask for more.
PS. if u worked for the real estate company the salary is much higher but
toooo much overtime works.
