連橫的《大陸遊記》與吳濁流的《南京雜感》為日治時期台人大陸遊記中最具代表性的兩部作品。連橫的旅行時間為1912年3月－1914年冬，吳濁流則是1941年1月12日－1942年3月21日，時隔近三十年，兩人的旅行動機、身分地位均有極大差異，當他們以日本被殖民者身分與中國相遇時，卻同樣在遊記中表現出難解的認同困境。連橫的關注層面以政治時事為主，吳濁流則注意到社會勞動階層生活，兩人指出了中國不同的社會問題，卻在思索解決途徑時透露出相似的民族情感。在遭遇認同衝擊時，連橫選擇以漢族本位主義追尋記憶中的父祖之國，吳濁流則以同情的理解態度來看待中國。在跨越或回歸的難題中，透過兩本大陸遊記的對照，可以更清楚看見日治時期前後階段臺灣人民所面臨的認同困境。

Lian Heng ''s Chinese mainland travelogue and Wu Chou-Liu''s Nanjing random thoughts are most representative Taiwanese’s China travelogues in Japanese colonial period. The travel of Lian Heng was from March 1912 to the 1914 winter, and the travel of Wu Chou-Liu was from January 12, 1941 to March 21, 1942. After nearly 30 years, the motives of these two travels and status are huge differences. However, when they traveled in China with colonized status, their travelogues showed intricate identity anxiety. Lian Heng mainly concerned to the level of political affairs, but Wu Chou-Liu noticed the life of the working class. They point out that the Chinese mainland different social problems, and they revealed the same national sentiment when finding solution. In different recognition impacts, Lian Heng chose to pursue his homeland in historical memory with Han parochialism, but Wu Chou-Liu looked at China through the sympathetic attitude. In the problem of leaping or return, we can more clearly understand the identity anxiety of Taiwanese in Japanese colonial period through these two Chinese mainland travelogues.
