The document summarizes a study conducted on Petaling Street in Kuala Lumpur, Malaysia. The objectives were to understand the origin and growth of illegal trade there, and how it affects the local economy and culture. Methods included site visits, questionnaires, interviews, and literature review. Interviews with locals revealed mixed views on Petaling Street, with some considering it still the cultural heart of Chinatown while others felt it had lost character. Locals were also mixed on whether illegal activities should be eliminated. The conclusion was that about 20% of shops would be closing in the next six months due to poor business and high costs in the current economy.
