The success of Secret Superstar in China is attributed to Aamir, because of his previous films 3 Idiots, Dhoom 3, PK and Dangal also getting an immense positive response from the Chinese audience.
But at the end of the day, Secret Superstar was still a female centric film, with Zaira Wasim in the lead role, and Aamir having a guest appearence. And Chinese audience loved Aamir for the content of his films. Secret Superstar won't have worked without Zaira's performance. This film was an average grosser in India, but a big Blockbuster in China. With the worldwide collections of 977 Crore gross, is Secret Superstar the second most successful female centric Bollywood film of all time behind Mother India. Could it be a bigger Blockbuster than Mother India as well?
Mother India is a very old movie, so its accurate box office data is not available. We can't tell exactly what would be its collections after adjusted for inflation. According to the site BOTY, after adjusted to inflation, Mother India worldwide gross would be 3920 Crores.

That figure is far ahead of Secret Superstar lifetime collection. But does it make SS second biggest female centric Hindi film of all time?
