In the traditional wedding custom in China, the engagement ceremony usually involves the custom of giving wedding rings. As a symbol, the wedding ring represents the promise of marriage and eternal love. However, whether the wedding ring must be purchased and whether it needs to be given at the engagement ceremony will vary according to the customs of individuals and families.

In modern society, some people choose not to buy wedding rings, but to choose other forms of engagement or wedding gifts instead. This is mainly because of different personal economic status, marriage view and cognition and attention to wedding rings.

In the case of engagement in shopping malls, merchants may set up some packages or promotions, which may include the option of buying wedding rings. Such activities are mainly to increase sales and promote the consumption of wedding rings. Therefore, whether to buy a wedding ring and send it at the engagement ceremony depends on your will and financial ability.

If you think a wedding ring is necessary, you can choose to buy a wedding ring that suits your budget. If you don't feel the need to buy a wedding ring, you can choose other forms of engagement or wedding gifts instead. Most importantly, your understanding and communication with each other is the key. You can decide whether you need to buy a ring according to each other's wishes and customs.
