Dear Van,

Today, in Vietnam often encountered many natural disasters such as floods, droughts, hail, tropical storms and other natural disasters. These are the most frightening things people are concerned about. Tropical storms often occur and cause most harm. It usually occurs in the rainy season and occurs most often in central Vietnam and coastal areas. It causes a lot of damage to people and property. First, killing people, livestock and poultry by the flood. Second, crop loss due to flooding. Humans become homeless and lose all their possessions. and many other damages caused by the storm. To prevent and fight against tropical storms, before it takes place, we must make preventive dikes, prepare adequate tools and food and other necessities. When storms occur, people must find safe shelters not to go out. After that, we have to overcome what hurricanes destroy, such as rebuilding houses, and many other things, if we live in that area, we should plant trees, protect the environment and many other practical things.

I am glad if you tell me about it in the next letter.

I look forward to your reply.

Your Best friend,

Ha Nhien.
