The news that his father contracted HIV through selling blood four years ago dealt a devastating blow to A Wen's (not his real name) family.
The 22-year-old Henan native was one of five mainland students who visited Hong Kong last Tuesday.
The students were here to share how Aids affected their families and how they battled the obstacles and discrimination.
Together with volunteers from local universities and children from single-parent families, the mainland students created paper artworks at the Standard Chartered Bank Building in Central.
They explained the meaning behind their artworks and explained how art can be used as therapy to help those suffering from trauma.
The art workshop was organised by the Chi Heng Foundation and sponsored by Standard Chartered.
