During the COVID-19 epidemic, the distance between people has become more alienated, which has also affected maritime economic activities. The traditional sulfur fishing, which was about to be eliminated, is facing a severe test. However, fishermen with optimistic nature still fish every night in the summer. They use sulfur-generated gas for ignition to gather fish by startling them, causing the fish to jump. The fishermen then use the smallest nets to catch the fish. The small fish caught are used to feed larger economic fish, and fisherman will immediately return to the port once the boat is full. The fishermen shout and scream with joy because they did not expect to encounter such a huge group of fish. The whole boat is so excited that even the photographers on the shore can feel this happy and surprising atmosphere.
