Luzon refers to Luzon Island in the Philippines today, and Jiaolaba is Jakarta in Indonesia. In ancient times when traffic was underdeveloped, the two places were far apart. The southwest of Huanggang Town, Raoping County, Chaozhou Prefecture is a natural harbor. Due to the blockade policy of ZF in Ming Dynasty, people could not go to sea to make a living, the port was depressed and the people were miserable.

According to legend, during the Wanli period of the Ming Dynasty, Raoping produced a hero named Patricia Lam Fung. He was dissatisfied with the rule of the Ming regime and was determined to break through the sea ban. He organized coastal people and prepared to move overseas on a large scale. To boost morale, Patricia Lam Fung said that we should make full preparations and start as soon as possible. By the time the imperial court sent troops to chase us, we had arrived at Jiaolaba in Luzon.

They made full preparations for going to sea and organized 62 large ships, which were equipped with sufficient food, daily necessities and a large number of seeds. They set sail from 300 gates and made an expedition to the Philippines. After arriving in the Philippines, they broke through the territory, married the aborigines and got along well. Now many people in the Philippines are their descendants.

Later, "Luzon called the trumpet" became a folk saying in Chaozhou, referring to a very distant place, which was beyond the scope of regulation.
