Xi 'an City Wall is the most intact section of the ancient city wall in China, and it is also one of the landmark buildings in Xi 'an. It is respected and revered by people because of its rich historical and cultural background. And "never part" is a symbolic statement, which is usually used to describe a belief or determination that will never be separated and unshakable. Those who leave a "oath" on the Xi 'an wall may take this sentence as an oath and swear love, friendship, affection and so on. On this wall, express their unswerving feelings.

At the same time, "swearing not to divide" can also be understood as a kind of inheritance and promotion of the traditional virtues of the Chinese nation. In the traditional culture of China, the virtues of faithfulness and honesty have always been respected by people, and the saying of "never opposing each other" is the embodiment of these virtues. In this era full of changes and uncertainties, let each of us keep in mind the meaning of "swearing not to leave home", stick to our own beliefs, keep a pure heart, and strive to become a true "believer" and make our own contribution to the harmonious development of society.
