It is my privilege to introduce Chinese Farmers' Harvest Festival, the first in China created for farmers in 2018. It falls on Autumn Equinox, which is the best time to celebrate the harvest.
This festival reflects the high priority the central government places on agriculture. All peoples’ involvement to celebrate it is welcome. In this way, the harmony and development of the Chinese nation can be enhanced.
In my opinion, farmers are encouraged to have their own ways to celebrate it. Actually, a variety of activities for the festival can be hosted, such as folk culture performances, food tasting, and sightseeing.

It is my pleasure to receive your letter. Knowing that you are interested in the Hong Kong-Zhuhai-Macao Bridge, I can’t wait to introduce it to you.
As the longest cross-sea bridge, it came into service in October, 2018. With this bridge, people living in Hong Kong, Zhu hai and Maocao can visit each other within one hour, making their life more convenient. What is more vital is that it can promote economic development of the three places.
In my opinion, I take pride in my country, where bridge-builders have overcome all barriers to construct this bridge. It does good to not only people living in these three places but also the whole country. If possible, you can enjoy the grand sight with me.

How are you? After getting to know that you are interest in the Wandering Earth, I am more than glad, as this film is my favorite. Now let me introduce it to you.
Written by Liu cixin winning in 2015, this film has gained great popularity since it went on show. We are not only attracted by its writer Li cixing winning Hugo Award in 2005, but its plot is also appealing. In this film, the Earth was faced with the greatest challenge. People didn’t abandon the Earth but saved it, wandering in the Universe with it.
In my opinion, this Chinese science fiction is great and makes us realize the importance of protecting our Earth.
