Literature Reference: 雨之施，物以孳，我何意于彼为。自周之先，其艰其勤。以有疆宇，私我后人。我祖在上，四方在下。厥临孔威，敢戏以侮。孰荒于门，孰治于田。四海既均，越裳是臣。—— 《琴曲歌辞 越裳操》 韩愈 The rain nourishes, and all things thrive. What is my purpose here? Since the early days of Zhou, through hardship and diligence, our land has been secured for our descendants. Our ancestors watch from above, overseeing the four directions. Their presence is majestic; none dare mock or insult them. Who neglects their gates, who tends their fields? When the four seas are unified, Yue Shang submits. From 'Yue Shang Cao' by Han Yu.
