In Hanoi, there are many beautiful landscapes, but my favorite is the Temple of Literature. This place is known as the first university in our country. Here each tortoise carries a stele representing the poinsettos here . The Temple of Literature is very beautiful with many rows of green trees. In front of the school there is a huge gate to welcome those who took the status quo exam from the past
