"At that time, my motivation was to make a profit and then fritter away the money. I didn't have a grander plan," she recalls.
In 2017, her family which was based in Chengdu, Sichuan province, decided to go back to their hometown, Shilan township in Huayuan county, to visit their relatives.
Ma Zhengbin, then-director of the culture station in Shilan, turned to her, hoping that she could help boost the township's Miao embroidery production.
"Initially, I felt reluctant, because I was a layman who didn't really know much about the craft or the industry," Shi says.
However, her mother persuaded her to give it a try.
She decided to launch a Miao embroidery company where local women could learn the handicraft for free.
At its inauguration, more than 400 fellow villagers came to sign up as embroidery trainees.
Faced with the unexpected crowd, Shi was surprised.
"I didn't realize that so many villagers were desperate for a job," she says.
Shi's idea soon took on a more charitable orientation. Each trainee would get a subsidy of 5,400 yuan ($802) by attending the three-month training course.
Shi Yulan, a villager in Shilan, is among the beneficiaries.
Once a migrant worker, Shi Yulan returned home and joined Shi Jia's company to make embroidery works, through which she was able to juggle her job and family commitments.
"After work, I can take good care of the family and spend time with my children, giving them a happy childhood," says the mother.
"I feel satisfied," she says.
To delve into the Miao embroidery culture, Shi Jia and her team have visited museums and browsed ancient books to collect traditional patterns. Adaptations have been made to some of the traditional designs to add an innovative shine to cultural and creative products such as clothing, ornaments, suitcases and fans.
Shi Jia has also brought the local art form to international runways, promoting the traditional ethnic cultural products at overseas fashion events and in foreign markets. However, the production capacity of the traditional handicraft is relatively limited and fails to ensure a stable, consistent income growth for locals.
Therefore, Shi Jia plans to promote local employment and the rural economy through the integrated development of primary, secondary and tertiary industries.
She has invested in the development of rice cultivation, tea plantation and lobster farming in Huayuan.
