Thirty Something (Chinese: 我的30定律; pinyin: wo de san shi ding lu; literally "My 30 Law") is a 2015-2016 Taiwanese drama television series created and produced by Eastern Television.

It stars Xiu Jie Kai, Kimi Hsia, Esther Liu and Samuel Gu.

First original broadcast began on December 12, 2015 on TTV airing every Saturday night at 10:00-11:30 pm.

He Mei Liang (Kimi Hsia) should be at the peak of her career and life, but she actually finds herself out of a job.

She used to work in medical equipment sales, but she let people walk all over her while she was too afraid to stand up for herself, so she ends up hitting rock bottom.
