    Have you ever tasted or perhaps heard of sugar painting? As fewer people choose to make sugar paintings, the traditional Chinese folk craft might have become a{#blank#}1{#/blank#}(distance) memory in some ways. However, a 38-year-old craftsman, Li Jiangzhong, is devoted to{#blank#}2{#/blank#}(keep) the art of sugar painting alive.

    Li worked as a miner for more than ten years. After{#blank#}3{#/blank#}mine closed down, Li turned{#blank#}4{#/blank#}housing decoration until he{#blank#}5{#/blank#}(force) to give that up due to a finger injury. Earlier this year, he discovered sugar painting, something he really had an interest in.

    Since there was no sugar painting craftsman in his village, he studied by{#blank#}6{#/blank#}(he) through large quantities of videos and information on the Internet. Li loved painting when he was young, and he found it easy to learn the skill in sugar painting. He soon mastered the skill and could make{#blank#}7{#/blank#}(vary) of sugar paintings. A sugar painting is made with{#blank#}8{#/blank#}(melt) brown or white sugar. Craftsman{#blank#}9{#/blank#}(basic) paint animals and flowers on a stone board with the syrup(糖浆). When the sugar cools down,{#blank#}10{#/blank#} appears is a piece of sugar art.

    Traditionally, we usually get a general impression of {#blank#}1{#/blank#} (stranger) by the way they shake hands, talk, or walk. However, in the age of social networking, first impressions are sometimes made {#blank#}2{#/blank#} looking at their profile photos on social platforms like Twitter or WeChat.

    These social images say a lot about our personality, according to a recent study, in {#blank#}3{#/blank#} researchers used a software to analyze the profile photos to find out whether there was a connection between a person's personality and his profile photo.

    The result reveals that open-minded people are more likely {#blank#}4{#/blank#} (pose) with an object in their profile photos. Their {#blank#}5{#/blank#} (excite) faces can tell how much they enjoy their experiences. Meanwhile, neurotic (神经质的) people tend to choose photos of objects rather than selfies to avoid {#blank#}6{#/blank#} (look) too miserable because of the strong social practice against a sad or angry {#blank#}7{#/blank#} (appear) in profile photos.

    Apart from the objects in profile photos, the colors used in them also show {#blank#}8{#/blank#} outgoing the owner is. For example, extroverts (性格外向者) {#blank#}9{#/blank#} (find) to have the most colorful profile images, as they want to emphasize their personality.

    Next time choosing a profile photo, maybe we should ask {#blank#}10{#/blank#} (we) first what kind of image we'd like to convey. After all, a picture is worth a thousand words.
