Centuries before Magellan, Chinese traders settled in what is now the town of Lian in Batangas province to trade with locals. When asked by Spanish settlers what the name of the place was, a Chinese trader named Li-An answered "Lian", which is how the town got its name. San Diego beach in Lian is a popular tourist destination known for its beauty and proximity to the mangrove rock formation, where visitors can stroll, take pictures, and enjoy the scenery.
