Nothing But Thirty (Chinese: 三十而已; pinyin: Sān Shí Ér Yǐ) is a 2020 Chinese drama television series directed by Zhang Xiaobo and starring Jiang Shuying, Tong Yao and Mao Xiaotong.^[1] The series follows the story of three vastly different urban women who have reached their thirties while facing challenges at a crucial stage in their lives, as they leave behind their youthful, carefree 20s to embrace the "adult" life of a 30-year-old, and ultimately decide to take matters into their own hands.^[1] The series began airing on Dragon Television and Tencent Video on July 17, 2020.^[1]

The story chronicles the life of three women with different backgrounds and different personalities.

Gu Jia is strong willed, and is both a housewife and a businesswoman. She helped her husband become the CEO of a fireworks company, and fought rich housewives who bullied her son. Wang Manni is rebellious, and is confident at both her workplace and at home. Zhong Xiaoqin is content with her average life, with a normal job and a husband who likes fish.

However, their lives are suddenly disrupted by external factors. Gu Jia begins to suspect her husband Xu Huanshan of having a young mistress, Wang Manni faces difficulties with sales and relationships, and Zhong Xiaoqin's idea of a perfect marriage is destroyed. How will the three women deal with the challenges of turning thirty?

Additionally a couple with a son close in age to Gu Jia's son Ziyan, who operate a food truck appear as silent characters. They occasionally interact with the main character and consistently appear at the end of the show before the closing credits.
