Daily SumUp

In the four years since she began driving solo across China, leaving behind an abusive marriage and longstanding expectations about women’s duties at home, Su Min, 60, has become an internet sensation known as the “road-trip auntie.”

She has driven to the foot of Mount Everest and camped on the beach in the tropical province of Hainan. She has been featured in an ad campaign about female empowerment and inspired a forthcoming movie starring a famous Chinese actress.

But one key step in Ms. Su’s emancipation eluded her: She wavered on whether to file for divorce, worried about how it would affect her family.

Until now. Last month, Ms. Su officially began divorce proceedings.

Her decision, she said, is a testament to how much she has learned to commit to her own happiness, and to the self confidence she has gained on the road.

But her experience in trying to end the marriage also shows the many barriers to independence that Chinese women still face. Ms. Su’s husband at first refused to divorce, and a legal fight loomed. Judges in contested divorce cases often deny petitions or force couples into mediation that disadvantages the woman, studies show, and they frequently ignore claims of domestic violence.
