How long to hike the Xihai Grand Canyon (West Sea Grand Canyon) Circuit?

Can someone give me estimated time required to hike the following route?

Start from top of the Yungu Cableway (White Goose Range) - Cloud Dispelling Pavilion - Xihai Grand Canyon - Monorail - Bright Summit Peak - White Goose Range (Yongu Cableway)

Can you route be reasonably done in 1 day and if so, approximately how long will it take?
