Gong Li's career has blossomed alongside China's rise to world-power status. She tells Jonathan Watts about her happy reunion with director Zhang Yimou, her days as a student dissident and her jealous fans. "Fans in China are very different from those overseas. In China, many people really love me and care about my life. But there is always some jealousy mixed up in this feeling of love. I think that is the big difference. Overseas, there is none of that." The Guardian interviews Gong ahead of the UK opening of "Curse of the Golden Flower."
