Giới thiệu chung về lũy tre làng em vào một ngày giông bãomik đang cần gấp , mong các bn giúp đỡ! 

During the Tet holidays, I was sent by my parents to see the water puppet show at the Ethnology Museum. It was very crowded here, people had to queue to get tickets. Luckily her family has a good seat. Water puppetry is a traditional art of the nation. Today, people re-perform the story of Tam Cam with water puppet, very interesting. The artisans are very good at manipulating puppets on the water like this. Voiceover for the character is also very consistent, not deviated from the operation. I enthusiastically watched the entire performance, it was much more interesting than watching cartoons, very real. From the character Tam, Auntie, Cam, Goby or Buddha are very similar described in the original. With smoke and water, the story becomes much more thrilling and fuzzy, very fairy-tale based. Everyone was very attentive, there was no sound. At the end of the show, everyone was satisfied and applauded the unremitting group. This is an interesting performance, I won't forget, I will definitely study well for my parents to show it again.
