The girls' individual archery event at the 2018 Summer Youth Olympics was held from 12 to 16 October 2018 at the Parque Sarmiento in Buenos Aires, Argentina.

Zhang defeated Spain's Elia Canales by six set points to two in the final, the Spaniard taking home the silver medal as the runner-up.

Each NOC was free to select its representative for the event according to its own criteria, irrespective of the archer who won the position at any one of the qualifying tournaments.

[3] Tromans-Ansell, who was coached by four-time Olympian Naomi Folkard and had switched from gymnastics aged 11 after a severe allergic reaction, had won the qualifying tournament held with the World Youth Archery Championships in 2017.

Speaking to the media afterwards, Zhang stated that although she was satisfied with her performance she was not going to enter the knockout rounds feeling complacent about having placing first.

[14] Both Tromans-Ansell and Jones were eliminated by seventh seed Valentina Vázquez Cadena in the 1/8 and quarter-final rounds respectively, the Mexican reaching the semi-finals to face Spain's Elia Canales.

Canales herself had finished eleventh in the ranking round with 645 points and showed improving form over the course of her three knockout matches, which included victory over sixth seed Clea Reisenweber of Germany, to progress to the semi-finals.

[15] Zhang meanwhile averaged twenty-eight points per set in her journey to the gold medal final, comfortably defeating Mst Radia Akther Shapla of Bangladesh, Kazakhstan's Alexandra Voropayeva, and Myanmar's Pyae Sone Hnin to advance to the semi-finals.

There she met fourth seed Son Ye-ryeong of South Korea, who had not conceded a single set in her three elimination round matches.

This drop in performance allowed Son to take the lead and break away, the South Korean claiming the fifth set soon afterwards to secure the bronze medal.

[17] In the gold medal final Zhang and Canales started off the match on an equal footing, both scoring twenty-six points to tie the first set.
