MY Travel Experience in China
During the summer holidays I visited a variety of regions in China.
My first stop was Beijing and of course the Great Wall. Without question it lived up to my {#blank#}1{#/blank#} (expect).
After a long journey, I reached Yunnan. With{#blank#}2{#/blank#}(it) minority villages and impressive landscapes, Yunnan had a lot to offer. One of my {#blank#}3{#/blank#} (enjoy) moments in Yunnan was during my visit to The Tiger Leaping Gorge. The climb over the gorge was at times exhausting {#blank#}4{#/blank#} always breathtaking. The views couldn't {#blank#}5{#/blank#} (imagine) in their beauty and they {#blank#}6{#/blank#} (leave) me with many great memories.
After taking a boat from the mainland I arrived at {#blank#}7{#/blank#} island province of Hainan. There I visited Baihua Waterfall. Floating on a pool of water at the base and looking up at the waterfall with a background of blue sky was one of the most {#blank#}8{#/blank#} (relax) experiences of my life.
Throughout China there are many ancient buildings and in particular ancient towns. Lijiang and Dali both have glorious {#blank#}9{#/blank#} (example) of this. It was remarkable to step back in time and get an idea of{#blank#}10{#/blank#} China might have looked like all those years ago. I thought the buildings were beautiful and full of history.
I had a wonderful time! China is both fascinating and beautiful!
