Chinese movie star Ziyi Zhang made a pact to learn English after she was forced to follow a man to a toilet in an airport when her flight from Los Angeles to Beijing was rerouted.

The confused Crouching Tiger, HIDDEN DRAGON star couldn't understand the signs or departure details when the plane she was on was forced to land at another US airport, so she took to following a man on board.

She explains, "I had to change planes. I got lost and I couldn't read the signs, so, for a few hours, I just followed a guy from my first plane who I knew was going to Beijing.

"When he went to the bathroom I stood outside and waited for him. I let him stay about 10 metres ahead of me."
