How to write the content of primary school students sending water to community security?

Pupils who want to send letters to Bao Xiaoan can write some words of thanks and blessings, such as "Thank you for always being here to protect us and make us feel very safe", "I hope you are happy and healthy every day, I hope your families are safe and healthy" and "Give you a glass of water, I hope you will not be too tired at work and take good care of yourself". You can write your name and class at the end of the letter, so that the small security guard can know which class of children gave him thanks and blessings.
