The Covid-19 pandemic is still ongoing, and it has had a great impact on people's lives and mental health. Medical research shows that keeping children healthy during stressful periods such as a pandemic requires more attention. What children experience during the pandemic will fundamentally affect their physical and mental health, learning ability, adaptive behaviour, and lifelong physical. Therefore, at this stage, the impact on children's mental health and development should be taken into account seriously, which can help children understand the knowledge of protection against the Covid-19 pandemic, and help them to channel their emotions and promote healthy development.
