The Manchus sent Han Bannermen to fight against Koxinga's Ming loyalists in Fujian. The Qing carried out a massive depopulation policy and seaban forcing people to evacuated the coast in order to deprive Koxinga's Ming loyalists of resources, this has led to a myth that it was because Manchus were "afraid of water". In Fujian, it was Han Bannermen who were the ones carrying out the fighting and killing for the Qing and this disproved the entirely irrelevant claim that alleged fear of the water on part of the Manchus had to do with the coastal evacuation and seaban. Even though a poem refers to the soldiers carrying out massacres in Fujian as "barbarian", both Han Green Standard Army and Han Bannermen were involved in the fighting for the Qing side and carried out the worst slaughter. 400,000 Green Standard Army soldiers were used against the Three Feudatories besides 200,000 Bannermen.
