This district is a swampy area so it's impossible to pass through in this place going in or out without passing through water. In Chinese language, this situation is called Bulo (no way out or no way in). In one of the Moro invasion in 19th century, a Chinese was assigned to watch the shores. After he saw the nearing vintas of the Moro, the Chinese went to the poblacion or town proper to warn the people. Since he could not pronounce the letter "r" he shouted Molo instead of Moro.
