Father's birthday should be taken seriously. Father's love is like a mountain. Now that you have grown up and have a job, you should celebrate your father's birthday well. Expressing your feelings will also make your father very happy. Knowing that you have grown up, he will feel relieved. After all, what parents want to see most is that their children grow up and become independent.
As for giving gifts, you can choose according to your financial situation. You can give your father a watch or a belt and tie. After all, he is a father, so you should be more solemn. But you can also give some warm little gifts. I don't think my father will care much about the gift. The main thing is your intention.
I recommend a real doll and make a family portrait. It is also a good decoration to put at home to add a warm feeling to the home. There are many such small gifts. You can choose and see. It will be helpful.
