LIHKG (Chinese: 連登; Cantonese Yale: Lìhn dāng) is a multi-category forum website based in Hong Kong. The website has gained popularity since the launch in 2016, and is often referred to as the Hong Kong version of Reddit. Threads with more up-votes and replies appear towards the top of topic sections and, if they receive sufficient votes and replies, they will ultimately be on the site's "Popular" section. The website is well known for being one of the main platforms for discussing the strategies for the leaderless anti-extradition bill protests in 2019.
