Let's get down to business. Now that you have decided to overcome your parents' obstacles, I can give you a set of strategies:
1 slide backwards. As the saying goes, a gentleman does not suffer immediate losses. If his family strongly opposes it, then you should follow them at home, eat and drink, and leave wine and meat in the Buddha's heart. You can also think, if you make your family unhappy, is it a crime to make them angry?
2 put facts and reason. Hehe, this is a common strategy. Avoid your intention to be a vegetarian and tell the general benefits of being a vegetarian. For example, vegetarianism can prolong life, slim down and reduce the incidence of cardiovascular diseases. Vegetarianism can make people more energetic.
Step 3 go around. That is to say something else first to induce parents to say something about themselves. You can do it.
You see, Jigong is a monk. Monks are not allowed to eat meat, but he will. In other words, it doesn't matter what he eats or does. The important thing is that my purpose is not to become a monk, but to cultivate my morality.
Hehe, if not, I'm paying attention to you. I am a smart person, QQ 5647394.
