Translation of presidency in German

We decided to fly directly to Hanoi and booked a flight for the same day. Before we left we still had some time to visit the War Remnants Museum. One could see the former headquarters of the South.
On the first day in Hanoi, we wanted to explore the town. It was the former capital of the North and today it is the capital of the entire country. There are tons of monuments and governmental buildings.
We exchanged numbers and they offered that we should contact them once we'd arrive to the capital. After dinner we bought some chocolate in one of the many stores, but it was not tasty, compared to Swiss chocolate.
