Dr. Luo Fengming is a respiratory disease expert from Sichuan Province.
He is leading a team of doctors from Chengdu's West China Hospital.
Due to the doctors' busy schedule, CGTN talked briefly on a ride to their hotel.
Dr. Luo told us it was very difficult to breathe when doctors put on the equipment and mask on. So they have to change shifts every 4 to 5 hours.
He also said the mask is very effective protection from infection.
More medical staffs are on their way to help Wuhan.
