Artist Ma Wen returns to Beijing's Olympic venue with new designs for the Water Cube, and a new outlook on traditional Chinese painting, Chen Nan reports.

Ma Wen caught a bad cold recently. For the past 30 days, she had been walking outside for hours after midnight in Beijing.

The 39-year-old visual artist was one of seven members on the core creative team for the opening and closing ceremonies of the Beijing Olympics and Paralympics. Now she is designing new outdoor illuminations for the Water Cube, the National Aquatic Center.
