On October 23, 2018，President Xi Jinping announced the opening of  the Hong Kong-Zhuhai-Macao Bridge (HZMB) at an opening ceremony in Zhuhai, Guangdong province.

    The HZMB, {#blank#}1{#/blank#} (locate) at the waters of the Lingdingyang of Pearl River Estuary, is a huge sea crossing, linking Hong Kong and Macao to the Chinese mainland city of Zhuhai. As the world's {#blank#}2{#/blank#} (long) sea-based project, the 55-kilometre bridge is the result of five years of research and another nine years of building. It has been described as one of the “seven {#blank#}3{#/blank#} (wonder) of the modern world” by the Guardian.

    The project{#blank#}4{#/blank#} (make) up of a 22.9-kilometer-long main bridge, a 6.7-kilometer-long tunnel and an artificial island off the bridge. It is designed with {#blank#}5{#/blank#} service life of 120 years. It can withstand a strong wind equal {#blank#}6{#/blank#} a maximum Beaufort scale 16. The bridge's engineers had to consider many environmental factors to protect the {#blank#}7{#/blank#} (surround) environment while building the bridge. Chinese white dolphins, an endangered species that lives in the area, {#blank#}8{#/blank#} (be) a particular concern.

    The HZMB will make {#blank#}9{#/blank#} much more convenient to travel between the three areas it connects. It will bring people in Hong Kong, Macao and Guangdong within a “one-hour living circle”, {#blank#}10{#/blank#}is expected to attract more visitors to the Guangdong-Hong Kong-Macao Greater Bay Area. It will be a transport link as well as a social, economic, cultural, and tourism connection among the three areas.

    Letters as a way of communication have long given way to phone calls and WeChat messages. But a TV show, LettersAlive, is helping bring this old way to keep in touch back {#blank#}1{#/blank#} the present.

    LettersAlive took {#blank#}2{#/blank#} (it) idea from a UK program, LettersLive, released in 2013. Both {#blank#}3{#/blank#} (show) feature famous actors and actresses, but there {#blank#}4{#/blank#} (be) no eye-catching visual effects or any regular showbiz(娱乐圈) activities. Instead, it's just a live event {#blank#}5{#/blank#} remarkable letters selected from a wide time span and a diverse range of subjects are read. There is, for example, a passionate letter from Huang Yongyu to playwright Cao Yu 30 years ago to criticize his lack of {#blank#}6{#/blank#} (create).

    Every letter is like a small piece of history. By hearing them being read, it's as if we are being sent back in time {#blank#}7{#/blank#} (experience) a moment that we would otherwise never have had the chance to.

    Compared to{#blank#}8{#/blank#} (publish) texts, letters also {#blank#}9{#/blank#} (natural) come with a personal touch. As well as celebrating the pain, joy, wisdom and humor, LettersAlive{#blank#}10{#/blank#} (commit) to promoting Chinese literature since first run.
