Gabi Rizea only discovered his talent for woodcarving three years ago, and has since put{#blank#}1{#/blank#} to good use, saving dozens of old tree stumps (树桩) from {#blank#}2{#/blank#} (remove) by turning them into impressive works of art.
Rizea became a woodcarver{#blank#}3{#/blank#} (complete) by accident. Three years ago, after buying himself a new chainsaw (链锯), he{#blank#}4{#/blank#} (start) “playing” with it on a block of wood. He tried carving a human face into the wood, and to his surprise, it turned out pretty good. Today, he is so good at woodcarving that his home city allows him to work his magic on old tree stumps and so far about 40 works of art{#blank#}5{#/blank#}(create) in the local parks.
“In 99% of the cases, the wood just doesn't match my ideas,” he said in an interview. “I first have to remove all the rotten parts, and sometimes{#blank#}6{#/blank#} is left isn't enough for my designs.”
Following his recent rise to fame, Rizea has been asked by many{#blank#}7{#/blank#} (city), including the capital of Romania to transform their old tree trunks {#blank#}8{#/blank#} works of art. He promised to honor their requests, but he will never repeat any of the artworks{#blank#}9{#/blank#} (find) in his home city.
In spite of his obvious talent, the Romanian {#blank#}10{#/blank#} (art) recently got into art school in order to fully master woodcarving.
