Answer 1

Hey mate

Here is ur answer

Rats were most common in the modern, newly built areas of Hanoi.

Adjacent to the French part of Hanoi was the 'native ' quarter which was not provided with any modern facilities.
The refuse of the old city drained during floods or rains, overflowed into the streets.
The large sewers in the modern part were ideal and protected breeding ground for rats.
The sewers also served as great transport system allowing rats to move around the city.
They entered well kept French homes through sewage pipes.
