牧惠先生《〈人迹〉序言》（刊于２００１年第６期《文学自由谈》）一文第一句就说：“上世纪８０年代初，自告奋勇当了《羊城晚报》总编辑的吴有恒司令（当年他是粤中纵队司令，我们这些老部下一直喜欢昵称他为“司令”）一声令下，我这个老兵终于重新放开手脚写杂文。”这句 The first sentence of Mr. Mu Hui’s Preface to “Human Traces” (published in “Literature Liberty Talks”, No. 6, 2001) states: “In the early 1980s, he volunteered as commander-in-chief Wu Youheng of the chief editor of” Yangcheng Evening News “ (At that time, he was the commander of the column in Guangdong, and our old men always liked to nickname him as ”Commander.") At this very moment, my veteran finally reopened his hand and wrote essays.
