How to write a message to invite someone for a birthday?

Dear grandpa, your kindness in raising children is as deep as the East China Sea and as heavy as Mount Tai! We sincerely wish you a long and healthy life, like that tall and straight pine tree, strong and green!

You are a big tree, sheltering us from the wind and rain; You are the sun, bringing light to our life. Dear grandpa, I wish you a long and healthy life. Happy birthday!

My best wishes are for your birthday, but love is with you all the year round! I wish you health and happiness!

Your birthday reminds me of your thoughtfulness and everything you have done for me. I just hope I can repay the happiness you gave me. I wish you all the best and endless happiness!

Today is a happy day. Today, you have worked hard for decades, and your children and grandchildren get together and enjoy family happiness. I wish you a long life and a bright future!

Dear grandpa, I wish you happiness and longevity. May health and happiness always accompany you!

Happiness is like the East China Sea, and longevity is better than the South Mountain.

Some of the above were written by me, and some were found. I hope it helps you.

In fact, as long as you give grandpa a birthday, he will be very happy, and everything you write reflects your filial piety! !
