Fan Bingbing and Chen Bo-Lin worked on the music video for the BUDDHA MOUNTAIN theme song. Bingbing and Bo-Lin held hands in the water. Bingbing at first was so nervous that she did not dare to go into the water. Bo-Lin played her bodyguard and protected her. They had to be romantic in the water. Bingbing honestly said that she was not a strong swimmer, after getting in the water she only remembered to keep swimming ahead and forgot the romance. She even had the greater challenge of opening her mouth to sing in the water, which to her was a highly difficult move.
The theme song originally was a duet with Bingbing and Bo-Lin, but he turned it down. Bingbing said that both she and the director tried to persuade Bo-Lin to sing the duet but he insisted against it. Bo-Lin explained that he was not suitable for singing and would rather honestly act.
