Can Chinese tourist viza extended in China or hong kong?

well chinese visa only can be extended from China but its not easy as you dont have any of your own relative or any company like if its work permit no problem and if your married to chinese then its easy to do too but still then chinese girl must have a good job like working for goverment if its private its not easy because the exit & entry department need prove and why you want to extend and stay much longer in china. Iam married so I got just recently for 6 months I had for 1 year from my country but only 30 days duration so I cannceled that and applied for 6 months duration its easy for me because my wife is working for goverment if not its very hard even for me . China is now very strict now . I say Europe is easy to travel now but china not at all.
