战国晚期,列国在河洛地区会盟频繁。这一地区成为会盟中心,应与秦国东向扩张首先将这一地区作为侵吞目标有关,很可能也与周王朝统治权力虽然衰败,然而依然余威残存有一定的关系。而当时“天下”观念得以普及,于是河洛地区作为“天下之中”的地位受到重视,应当也是原因之一。 In the late Warring States period, all nations frequently met in the Heluo region. This region has become the center of the League. It should be related to the first expansion of the Qin Kingdom as the goal of embezzlement, and it may well be that although the ruled power of the Zhou dynasty deteriorated, there still remains a certain relationship. At that time, the concept of “world” was popularized. Therefore, the status of Heluo as “the best of the world” was taken seriously, which should also be one of the reasons.
