That City was a political comics series published by Hongkongese comics artist Justin Wong in a special column published in Ming Pao's supplementary pages Sunday Ming Pao from 2020 to 2021. Originally titled This City, it criticized the events of Hong Kong at the time. Later, the Hong Kong national security law was passed, which considered comics to be more seditious than writing. The column was therefore renamed That City. In 2021, due to citizen reports to the police about his work, Wong left Hong Kong for London in an emergency trip. This comics series turned out to be his farewell work to Hong Kong. /The book That City collects all 52 of the comics published during serialization. It centers on Hong Kong's political environment, civic awareness, and social trends in recent times. The book expresses mourning for the lost Hong Kong in people's hearts, denunciation of the omnipresent state surveillance, forewarnings directed towards those uncaring, and warmth for local Hongkongers. /Wong's style, influenced by American comics artist Chris Ware, is distinctive in its assemblage of panels following the principles of graphic design and geometric ordering. Although the themes are political, the tone is not harsh or judgmental. Instead, through abstract, simple, allegorical imagery, fun and experimental visual compositions, and poetic, philosophical, and humorous text, Wong's work creates space for readers' reflection about heavy issues. These poignant comics tell the unseen yet powerful courage of the people of Hong Kong, their secret struggles, and silent protests.
