M:Hi,Linda.Nice to see you again.Did you have a good time on vacation?
W:Yes.I went to Beijing with my aunts.We had a great time there.
M:That's cool.Did you do anything interesting there?
W:Sure.We mostly visited different museums there,like the Palace Museum,we tried special foods in Beijing.But the best part was climbing the Great Wall.It was really amazing standing on the top the wall.I wonder how hard the ancient people worked to build such a great object.
M:That's right.It did take a lot of people a long time to build the Great Wall.
