It took the Indian unit some days to work in harmony with the Chinese unit. Four interpreters were hired to facilitate coordination between the Indian and Chinese units.
Choreographer Pony Verma recalls how they had to first learn to count one to ten in their language. It was not at all easy getting their accent, but after a couple of days, they managed.
The Chinese dancers had to be told time and again that they had to start their steps after the count of four.
It is known from the sources that Verma said, Chinese had never seen a Bollywood unit. It took them as much time to familiarize themselves with the Bollywood form of dance.
Apparently, Akshay Kumar was dressed up as a king and Deepika Padukone as his queen for the song sequence.
The song was shot at various places, like the Forbidden City and Shanghai. Verma says that she would have loved to shoot a portion of the song at the Great Wall of China, but an action sequence for the film had already been scheduled there.
