This year, the school let us visit the Air Defense - Air Force Museum. The museum of "steel soldiers" has a large and beautiful campus located right on Truong Chinh Street. From outside the gate, we could see a very large building with dozens of stone steps leading up to the main display hall of the house. The museum has modern architecture but is also very sturdy with large pillars, all of which makes us not only overwhelmed by the heroic historical feats learned here but also feel small.I feel very happy and proud. The picnic brought a lot of useful knowledge and I will never forget this useful sightseeing trip.
