1. According to international and traditional Chinese customs, wedding rings need to be purchased by the man as a gift to the woman, which is a common and widely accepted purchasing method.
2. In the matter of marriage, when the man purchases a ring, it shows that the man is the one taking the initiative and also means that the man wants to take the initiative to marry the woman, which is another manifestation of the man's sincerity towards marriage.
3. The man's purchase of a ring is another display of economic strength and a matter of his dignity. When a man buys a ring, it will make the woman feel that you are considerate and sincere, and that you value yourself more. This will leave a good impression on the woman and earn her respect. If the woman buys a ring, others will gossip about the man behind his back, which undermines his dignity.
