The colorful houses on both sides of the streets in Boca can be traced back to the late nineteenth and early twentieth centuries, when poor Spanish immigrants came to this place and built many simple iron houses, but the romantic atmosphere in their bones did not allow them to leave their houses dark, but went to the nearby harbor to get some paint left by the painting boat to paint them. My hut, this custom has continued, but it has become Buyi's most famous scenic spot, but also a favorite place for photographers. These paints are sun-resistant and waterproof paintboat paints, so they are durable and fresh and will not be easily mottled. In addition to colorful houses, Boca Youth Team and Tango are also Boca's business cards. There are free Tango performances at restaurants and bar doors from time to time to attract tourists and enjoy the performances while eating.
