I had deliberately postponed it until mid-September, thinking that the rainy season would be better, but it was still raining and muddy. Finally, I understand how people here love to wear masks. The original rainy season is muddy. When the rain passes through the sunny road, the dust will fly and the passers-by will become "human flesh vacuum cleaner". It is commendable that the ancient city buildings are well preserved and have a strong sense of history. Like India and Sri Lanka, people live peacefully with animals. In addition to dogs in the streets (fortunately, habitual people are not too fierce), pigeons, sparrows, cattle, monkeys, crows and so on are also common, except squirrels, which are common in India and Sri Lanka.
