South Korean actress Song Hye-gyo said Saturday she feels like going back to a beginning actress when she works on a film in China.

"I'm filming my first Chinese movie, and there are many differences from working in South Korea," Song told at a press conference held on the sidelines of the Busan International Film Festival. "There are also some difficulties with doing lines in Chinese, and all make me feel like I'm new again."

She is currently working with director Wong Kar-wai of China' s Hong Kong, making "Legend of Yip Man."

Song said she has mostly played static characters in her career, and her role in the Wang's movie is quite similar, yet she has learned a new lesson.

"I've learned how to act by using my body. Director Wang has taught me how to express feelings with the use of body," said Song.

Song attended the Busan International Film Festival to promote her new South Korean film, "A Reason to Live," directed by local filmmaker Lee Jeong-hyang.

The actress said that she can find some similarities between both directors, Wang and Lee.

"The two directors pay attention to the details of the movies, and cares about every little thing of the movies," said Song.

The actress said she expects her first Chinese movie to be released sometime next year as it is in the final stage of the production.
