[11] He competed at the Asian Youth Games, winning the bronze medals in the boys' singles and mixed doubles, partnered with Chen Yufei.

[7][16] Shi, however, did not have a good year in 2015; his best showing was at the China Open, where he reached the quarter-finals of the tournament, losing to Son Wan-ho of South Korea in three games.

[18] However, his form improved later in the year and he won his first senior title on tour by winning the Indonesia Masters after his compatriot Huang Yuxiang retired in the second game of the final with Shi leading 21–12, 11–0.

[20][21] Shi then continued his rich veins of form by winning the Bitburger Open, beating India's Sourabh Varma in the final.

[47] Shi played as the first men's singles against Kento Momota of Japan at the 2020 Thomas Cup semi-finals in Aarhus, Denmark.

The internal ban was due to the infamous incident from the 2020 Thomas Cup competition and the immature comments that he made after the match.

[50] At the 2022 BWF World Championships held in Tokyo, Japan, Shi returned to action for the first time in 10 months, after serving a ban, and beat Azerbaijan's Ade Resky Dwicahyo and Denmark's Rasmus Gemke in the first two rounds but lost out for a place in the quarter-finals after losing to Indonesia's Anthony Sinisuka Ginting in the third round.

[63] His inconsistent form continued at the Badminton Asia Championships held in Dubai, where he lost to Lee Cheuk Yiu in the second round.

[65] In the subsequent months, his performance notably improved, as he advanced to the quarter-finals in 5 out of 7 tournaments, with semi-finals appearances at the Korea and China Open.

[72] However, Shi's streak of seven consecutive quarter-final or better appearances at the world tour finally came to an end with a surprising defeat on home soil in the second round to Christo Popov at the China Masters.
