Family tourist visa

I'm from Jordan lived here in Guangzhou China ... And I visit Italy many times .... This year I asked the agent apply for me and my wife and my son a tourist visa for vacation this summer .... The agent answer me your wife and the babe Cannot take visa from China .... I have resident permit here in PRC for more than 9 years + my wife already live with me here and already I do for them the residents visa to stay with me in PRC ..... I just didn't understand why I have to go back turkey to make for them the entry permit .... ( my wife and my son they have a turkish passport) I just want to know what to do ... And thank you so much
