Check your ATK before traveling
Wear a double mask when using public transportation because it’s crowded.
The elderly in the high-risk group are especially cautious.
It’s best to be in a small group in the family.
Avoid crowded places if not necessary.
This Songkran, the medical personnel are still preparing. Especially after Songkran, the cases will definitely increase. Should be busy until the end of May. Have a safe trip back and forth both accidents and covids.
