Transfer Salary money from China to India ? (Shanghai)

Dear People
I am an Indian National currently working in Shanghai and my salary is paid in RMB in my China Construction Bank Salary account.
I need to transfer money regularly to my accounts in Indian Banks to pay for various fees in India for my family.
what is the best possible option to do the same with minimum hassle and less fees on foreign exchange transactions.
Kindly post your replies soon .
