In our traditional festivals, Tomb-Sweeping Day is one of the 24 solar terms. Tomb-Sweeping Day is a public day for people to worship their ancestors, and there are generally no greetings.

If you insist: you can say: Qingming happy. Only ghosts are happy, people worship and have food to eat, so they are happy. )

You can also say: happy spring, (Qingming is spring)

Of course, you can also say: Happy ancestor worship. (Because the main job of this day is to worship ancestors)
