Visit my parents-in-law twice a year

I am a Turkish national but I visit my wife's parents (in China) twice a year; each visit is usually 2 weeks long. Every time I apply for a Q2 type at the embassy, I am only given 6 months double entry one even if I request a longer validity and applying visa twice a year is quite time consuming.

Is it possible to convert my Q2 type into some sort of multi-entry long term residence permit in Local Entry Exit Department in China?
