自1996年，食公子最早以“廖聖然”喺《風味》、《蘋果》、《旅行家》撰文飲食文章。2000年蟬過《風采》採寫美食專欄至2014年7月20日。2007年，廖城蘭突然轉變書寫飲食專欄嘅文風，從資訊型飲食雜述復加入政治元素。
Since 1996, Eat Gongzi was the first to write food articles in "Flavor", "Apple" and "Traveler" with Lin Liao Shengran. In 2000, he wrote a food column in "Style" until July 20, 2014. In 2007, Liao Chenglan suddenly changed her style of writing food columns, adding political elements from information-based food miscellaneous narratives.
