Liu Jinfeng has been an aircraft maintenance engineer at Taikoo (Shandong) Aircraft Engineering Company ever since he graduated from university 16 years ago in Jinan, capital of Shandong province.

Through diligence and hard work, he became a highly-skilled engineer at the company.

"Just like humans need regular physical checkups and cars need regular inspections, the same applies to aircrafts," Liu said.

"Aircraft maintenance engineers are basically doctors for aircrafts. Our priority is to keep the aircraft in safe and reliable condition and ensure that flights can take off on time."
