"In official histories," says Liu Wei-kai, "topics like the Northwest Army or the Blue Shirts have been relatively ignored, and it has not been very easy to find relevant materials. Biographical Literature articles opened the path, and stirred up even more sparks."
「在過去官方的史學研究中，像西北軍或藍衣社都是比較冷門的一環，也不大容易找到相關的資料，『傳記』的文章等於開了頭，也撞擊出更多的火花」，劉維開說。
