跟弟弟拜年怎么说英语

To greet your younger brother for the New Year in English, you can say:
"Happy New Year, little brother!"
"Wishing you a wonderful New Year, brother!"
"I hope this year brings you joy and success, dear brother."
You can also simply say:
"Happy New Year, brother!"
If you want to be more formal, you can say:
"I wish you a very happy New Year, dear brother."
I hope this helps! If you have any other questions, please don't hesitate to ask.
