The old lady is 89 years old. Today is her birthday. What should I say to her?

Of course, the blessing to the old man is to wish him happiness as the East China Sea and longevity as the South Mountain. Then the most common sentence must be wishing the old lady a long life, because she has reached this age and her neck has been buried in the ground. Then the most important thing for him at this age is longevity and health, so that he can live longer. Then he is better than others, which is also a point he pursues in life. So, I think you can use the above words to express your birthday wishes. Of course, you can also say that you think about some good wishes from the heart, which may leave a deeper impression on his mind.
