Fang Zheng is from Hangzhou and majoring in IT at Monash University. He came to Melbourne alone when he was 12 years old and now lives in Melbourne with his sister. He is very cool and speaks very simply. He answers questions with just "um" and "ah", and reporters outside the field can't do anything about him. Fang Zheng loves music. His sister told reporters that Fang Zheng is a musical boy at home. As long as he is at home, his singing will not stop. Fang Zheng is very strict with himself. When he practices singing, he must carefully consider every sentence and word to find the right feeling. In the promotion round, accompaniment can be used, but Fang Zheng still chose to sing a cappella. His song "Quicksand" conquered the judges on the spot and convinced the contestants in the same group.

In the first round, the Australian fast boy chose the Cantonese version of "Little Things in the Big City" to impress people. However, he was not promoted and has yet to be determined to enter the comprehensive charm rental for PK. Fang Zheng's "Back to Back Hug" helped him advance successfully. The judges praised Fang Zheng, who "came from afar", for being worthy of the word "promotion". Fang Zheng was also the second contestant to advance from overseas.
