Sun, coach head back to the pool

Champion swimmer and mentor reunited after acrimonious rift

The tension between star swimmer Sun Yang and his long-term mentor has eased and the duo will return to practice pool on Monday.

Double Olympic champion swimmer Sun (pictured) finally apologized to coach Zhu Zhigen after making his coach of 10 years angry with a request to replace him last month. Sun posted a photo of him hugging Zhu on his micro blog on Saturday.
