How can we get Q1 visa

I am from Pakistan, married here in china in 2003.
Having 3 children, 2 Chinese nationality and 1 Pakistan nationality. We have our own home in mainland PRC. Many times I tried for Q1 type in PRC embassy Islamabad but unfortunately they told me next time and issued Q2. Its also takes 3months to get the entry permit, I afraid that if there occurs any health problems with my spouse I can't reach early to take care of her. Is there any way to fulfill this serious problem? (all Pakistanis face same problem and few take help from agent if they require urgent entry permit)
