Trainee flight attendants at College of Civil Aviation in Chengdu, Sichuan Province, central China are practicing bizarre skills using chopsticks and various other handy items so as to become official stewards and stewardesses.

As Daily Mail reports, the students are balancing books on their heads for a straight posture while they are biting on chopsticks to achieve the perfect smile. They also place a piece of A4 paper between their knees when standing straight.

One of the women said she had to master acrobatic skills in order to become a successful flight attendant.

Speaking to reporters, student Zhang Tongtong said: ‘We not only have to balance a bottle on our head for three minutes, we have to keep smiling at the same time to demonstrate the elegance of flight attendants.

‘In order to pass, we often practice by ourselves with a bottle. This is not just for the examination, it’s to help us to be more graceful,’ she said.

The teacher at the college Xu Liqing explained the her teaching methods saying that In our normal training, we use wine bottles to help practice standing. This is to train the students’ gesture as well as their confidence.
