China Aids Walk is the nation's largest awareness and fundraising event focusing on HIV discrimination.
Since 2012, people from a wide range of backgrounds have been invited to take part in the event at China's Great Wall.
The event aims to educate the public about HIV, advocate for equal rights for those infected with the virus and raise funds for communities affected by the disease.
The group also organizes walking events in six other Chinese cities, drawing in more than 4,000 participants.
Martin Yang, director of China Aids Walk, spoke to us about the goals of the organization.
