Answer:
In 2020, the world has suffered from a terrible pandemic which goes by the name Corona Virus. Lives of all people were turned upside down. Governments imposed lock downs all around the globe. At that time, teachers showed tremendous resilience and determination and taught their students diligently. Most of them were not familiar with the new way of teaching that was required, via video conferencing.
Teachers made sure to perform their duties even in the the most difficult of the situations the world has ever faced and came out victorious. The least we could do is show appreciation towards their hard work.
