about passport lost,,, i am from bhopal (m.p.) i lost my passport in jiamusi (china)..please help me

Vikash, you should report the situation to the local police station, and then you can get the loss certificate. Take the loss certificate to the embassy of India in PRC to apply for a new passport.
After that, update your registration information at the local police station and take the new passport to the exit and entry administration to apply for a new visa.
