By the 1980s and 1990s, Kowloon Walled City had become a sprawling slum, home to over 33,000 residents packed into an area of just 6.4 acres. The city's density was staggering, with buildings stacked haphazardly, and makeshift structures sprouting up on rooftops and alleys. The air was thick with the smells of cooking oil, sewage, and exhaust fumes.

Residents of Kowloon Walled City lived in squalid conditions, with many families sharing cramped apartments and makeshift homes. The city's infrastructure was woefully inadequate, with narrow streets and alleys that were often impassable due to piles of trash and debris. Sanitation was a significant concern, with many residents relying on communal toilets and showers.

On January 14, 1993, the Hong Kong government began the process of evicting residents from Kowloon Walled City. Over the next few months, thousands of residents were relocated to public housing estates, marking the end of an era.

The demolition of Kowloon Walled City was completed in 1994, and a new park, Kowloon Walled City Park, was built on the site. Today, the park is a tranquil oasis in the heart of Hong Kong, a far cry from the squalor and crime that once characterized the city.
