I. Fill in the gap with one word from the box.

I’ve just been back from my vacation in Hanoi, Vietnam. In this trip, I had a chance to visit some (1) villages that produce the finest craft works exported over the world.
The very first place I (2) foot on was Van Phuc silk village, the cradle of best silk in Vietnam once. I totally fall in love with many colourful clothes, hats, bags, tie... made of authentic silk. Then, I moved on to Bat Trang ceramic village, the most famous and (3) pottery village in Vietnam with a nearly 1,000 years old historic development. Here, I visited a small family factory to see how the (4) form, paint and glaze with unique products and have a chance to practice my talent with wet clay and a mould. Afternoon, I continued to visit Dong Ho folk painting village, (5) the traditional woodblock paintings are preserved. I was completely impressed by the folk paintings made by the local (6) artisans with natural materials and colors. Each painting is (7) handmade on paper of the Dzo tree and is coloured with other natural materials and its glittery surface is finished with oyster shell dust.
I took home a lot of handmade (8) which were later given to my family and friends.
