Social enterprise Geylang Adventures, founded by SMU Master [of Tri-Sector Collaboration] student Cai Yinzhou, is co-organising guided tours of the Cheng Xing Provision Shop this weekend. The shop at 229B Geylang Road, which sold items like cigarettes, vintage mugs and joss sticks for more than 70 years, closed down last year. There will be two guided tours on Sunday, co-organised with media company Our Grandfather Story, to pay tribute to the business and its owners. Yinzhou said that shopkeeper Yeo Li Ying closed the shop for good last year, partly because of falling sales with the Liquor Control Act in 2015 and her husband's death in 2016. Mdm Yeo approached Yinzhou for help to sell her items, as she had no space to keep them in her new Yishun home.
