What should I write when sending an epidemic banner to the township government?

Express gratitude.

When the township government sends an epidemic banner, it can say that we work together to fight the epidemic and build fortresses on the front line of prevention and control.

Expressed my heartfelt gratitude to the frontline staff of the government for their tireless efforts, courage to take responsibility, dedicated service, protecting people's health, and working together to fight the epidemic in epidemic prevention and control.
