The two speakers come from different professional fields. Dr Wu is a civil and marine engineer, an urban planning designer, and a senior member of the China Association for Scientific Expedition. He has travelled extensively around the world. In 2015, Dr Wu founded the HADALX club, which is dedicated to conducting scientific research and exploring the unknown world of the deep sea through innovative scientific techniques and engineering. His goal is to promote public awareness of the ocean and provide marine science education for young people.

On the other hand, Professor Qiu is a biology expert. He has discovered 17 new species in just ten years. When numerous fireworms appeared on a Hong Kong beach in 2018, he led a research team to identify the species, and discovered and named a new species. In 2021-2022, Professor Qiu and his team published about four new species of sun coral, demonstrating the high biodiversity of corals in Chinese waters.

After exploring the deep-sea, Professor Qiu introduced discoveries of marine species. For almost 20 years, Professor Qiu and his research team have dedicated themselves to protecting marine biodiversity. He discussed the new species that they have discovered in the deep waters of the South China Sea and the shallow waters of Hong Kong, such as rare beard worms without a mouth or a digestive tract, Catillopecten margaritatus, and new species of box jellyfish. He also elaborated on the research team's in-depth studies regarding  the population connection and conservation values associated with these newly discovered species. 

The Q&A session after a seminar is always very popular, and the students showed great curiosity and interest. Their questions covered a wide range of topics, including hot topics in marine science, future career opportunities, the technology for mapping deep-sea terrain, and biodiversity conservation. Dr Wu and Professor Qiu both noted that our understanding of the deep sea is still very limited. There are many unknown species yet to be discovered, and numerous disciplines can be applied to ocean exploration. Dr Wu and Professor Qiu strongly encouraged the students to pay close attention to the oceans, as well as the development of marine science and technology, and to consider exploring the oceans in the future.

Dr Esther Chan, Deputy Chief Executive Officer of YCYW, delivered a speech after the lecture. She expressed her gratitude to Dr Wu and Professor Qiu for sharing their expertise about deep-sea exploration and marine species, thereby enriching our understanding of various scientific fields and sparking everyone's curiosity. "This year, we have established a new programme called the 'The Seeds for the Future'. Here, we are dedicated to collaborating with institutions around the world, just like HADALX and Hong Kong Baptist University, to enrich our school curriculum, as well as develop super-curricular programmes that extends our students learning beyond the classroom."
