遼興宗曾經各有一次以遼西京和獨盧金為冬捺鉢駐帳地，至於遼道宗則有四次以獨盧金為冬捺鉢駐帳地，但是其中有三次在獨盧金逗留一段時間之後，又從獨盧金前往遼西京。因此在這六個年份，此二地點也就成為宋使節出使遼國的目的地，是宋使節晉見遼皇帝與進行交聘活動的地方。但是因為目前存留有關宋使節前往遼西京和獨盧金的記載相當不足，並且有模糊不明與矛盾之處，因此筆者擬在本文中，針對這些史實進行論述與考證的工作。

The Liao Xing Zong had ever to Liao Xi Jing and Du Lu Jin once respectively as the station of Dong Na Bo. As for the Liao Dao Zong, there were four times for the Du Lu Jin as the station of Dong Na Bo, however, stayed at Du Lu Jin three times for a period of time, and then went from Du Lu Jin to Liao Xi Jing. Therefore, these two places became the destination of the Song Dynasty's envoys to the Liao country for these six years, where the Song envoys met with the Liao Emperor and engaged in activities. However, the current records about the Song Dynasty's envoys to Liao Xi Jing and Du Lu Jin are not only inadequate but also so vague and contradictory till now. This author intends to discuss and research on these historical works from this text.
