You should follow your own heart and thoughts. Many people can't feel your heart. In my opinion, it depends on your present life and the reason why you go to your biological parents. If your adoptive parents treat you well, you are treated well.
Then you should talk to your biological parents and try to get their permission before you do it. Or you'll break their hearts. In this state, in fact, there will be a lot of uncertainty in finding your biological parents.
They have a good life, and you have two more close relatives. If their life is not good, will you undertake the obligation to support them? If you don't live well at your adoptive parents' house.
It should be more likely to find your real parents. The lack of affection and care will make you want to find your biological parents more, and you have gained affection that you have never had before. This is a very personal question.
Everyone may think and feel differently. Some people may be very eager to know their biological parents and birth background, while others may prefer to focus on their present and future rather than care too much about the past.
If a person knows that he is adopted, he may face some emotional and psychological challenges, such as curiosity, uncertainty, loneliness and so on.
In this case, he may consider looking for his biological parents or other relatives to get more information and understand his life experience. Finding biological parents may also face some difficulties and challenges.
For example, the lack of information, the reluctance of biological parents to meet each other, and the emotional impact caused by the revelation of the secrets of life experiences.
Therefore, everyone needs to weigh the pros and cons carefully when deciding whether to find their biological parents.
Also consider emotional and psychological endurance. You can also seek the help of psychological counselors or related institutions to get better support and advice.
