D

    Nowadays, phone calls and messages help us communicate with others more often. It means that we seldom write letters now. But a TV show. Letters alive, is bringing back this old habit.

    Letters Alive invites famous actors and actresses but there are no funny jokes or different competitions. Instead, only one person walks up to a microphone and reads a letter. The letters were written by people from different times in history. For example, in one episode(集), they read a letter written by the famous writer Xiao Hong to her younger brother in 1941. The letter shows that Xiao Hong missed her brother so much and had great hopes for his future.

    “Every letter opens another world for us, " said Guan Zhangwen, the director of the TV show. “It seems that we can experience the real lives and feelings of the writers". Since its first episode on December 5, 2016, Letters Alive has been widely praised. Many audiences(观众)say that it has provided a breath of fresh air to today's TV shows.

    Besides Letters Alive, some other cultural TV shows have also attracted(吸引)Chinese audiences. They include the Chinese Poetry Conference, a traditional Chinese poetry competition and Readers, a program that invites people to read poems and articles they like or wrote. It suggests that cultural values and true feelings are becoming our interest.
