Can renew China passport in Malaysia ?

Hi, I am Malaysian, my wife China Passport valid date is on June 2018. If she planning to go back China during
Feb 2018 and back to Malaysia by March 2018. The problem is when she booked Air Ticket , the Airline company not allow because her passport validation date is less than 6 months. Can China Embassy in Malaysia allow her to renew her passport now in Malaysia ?

Thank you.
