By the time Mr. Wan reached the 55-year-old retirement age, as some of his children had not started working yet and he did not have much savings, he therefore decided to quit his job and open a grocery store to earn money to fund his retirement. Although Grandma Leung was still working in a factory, she had to resign and help her husband run the store. As was common at the time, the couple used wire meshes to enclose the open space in front of their home and opened a grocery store there. Noticing that people loved to drink fresh fruit juices but could not buy them from supermarkets, Mr. Wan spent HK$4,000 on a juicer, selling both fruits and fruit drinks from the new store. Their store became a gathering place of neighbors.
