The only female technician in the Nanning Public Works Section of Nanning State Railway Nanning Bureau: soft shoulders bear heavy weight and bloom with youth. Wu Mengxuan set a small goal for himself: to work hard to learn business skills and become a technical expert.
She gets up at six o'clock every morning to memorize the "General Speed Railway Work Safety Rules" and goes to the training ground at seven o’clock to continue practicing. She humbly asks the teacher in the team for advice when she doesn’t understand.
