1. Open-minded and cautious: be open-minded and tolerant, be cautious about everything before and after marriage, properly handle every detail, and resolve conflicts in time, instead of quarreling at first sight. In addition, we should think more about the relationship between the two parties after marriage, take into account each other's feelings and preferences, uphold fairness and justice, and put family harmony first.

2. Effective communication: We should be prepared to communicate with each other, and we should respect each other's opinions, treat each other politely, understand each other's feelings, and negotiate the interests of both sides, instead of relying on our own will and traditions to act, so as to maintain good communication and avoid it.

3. Limit the amount of alcohol consumed by both parties: For example, for family festivals or weddings, before that, both parties should give up drinking and smoking, and limit the amount of alcohol consumed by each person during the activities, and cooperate with local alcohol restriction measures to avoid quarrels caused by excessive drinking, which in turn will lead to marriage events.

4. Establish in-laws: Before the wedding, efforts should be made to establish in-laws between the two parties to reduce the sense of estrangement between ethnic groups. Both parties and their relatives and friends should communicate more, try to establish friendship, reduce quarrels and maintain a pleasant atmosphere for the wedding.

5. Avoid wedding control: Parents should respect their children's autonomy and not over-control, but encourage and support their children's wedding preparations, respect their opinions, and jointly create a happy and harmonious wedding atmosphere, abandon traditional stereotypes and be real family and friends.
