Origin Story
话说古代有一座大山，山脚下长着一棵古老的树木。这棵树历经了无数的风风雨雨，它的根系深深地扎入地下，盘根错节，如同巨人的手臂般牢牢地抓住泥土。即使狂风暴雨来临，这棵树也屹立不倒，因为它根深柢固。许多年轻的树木在其旁边生长，却常常被大风刮倒，而这棵古老的树则纹丝不动，像一位沉默的卫士，守护着这片土地。它用自己的生命告诉人们：只有根深柢固，才能经受住时间的考验。许多人羡慕这棵古老的树木的强大生命力，都想学习它根深柢固的品质。他们开始学习努力，打好基础，为自己的未来奠定坚实的基础。正如这棵树，它的根系深入地下，深深地扎根于土壤，以汲取足够的水分和养料，才能茁壮成长，抵御风雪。因此，人们总是说，打好基础才能拥有坚实稳定的未来，才能立于不败之地。
It is said that in ancient times, there was a great mountain, at the foot of which grew an ancient tree. This tree had weathered countless storms and winds, its root system deeply embedded in the ground, intertwined like the arms of a giant, firmly grasping the soil. Even when violent storms came, the tree stood unyielding, because it was deeply rooted. Many young trees grew beside it, but were often blown down by strong winds, while the old tree stood unmoved, like a silent guardian, protecting this land. It showed with its life that only those who are deeply rooted can withstand the test of time.
