Taiwan female musical duo ASOS, composed of two sisters Big S (Hsu Xiyuan) and Small S (Hsu Xidi) attended a promotion for a clothing brand at Peking University Hall in Beijing on Sunday.

Unexpected welcome from the students surprised ASOS. More than 700 people flocked into the hall, including about 500 students.

Many students who had no tickets had to stand outside the hall in order to take a closer look at these sisters.

During the event, ASOS shared tips of how to dress well with students. Small S said that in the past she didn't know how to dress well and was often laughed at by Big S, who was always leading the trend.

When students asked if she had ever considered cosmetic and body-building issues for her babies, Small S, mother of two daughters, said yes. "I'm planning to train them to do push-ups now." Her humorous reply amused the audience.
