Generations and generations of fishermen have lived on boats on Beijiang River in Guangdong province.In 2009,the Shaoguan City government introduced resettlement project,which provided low rent houses for the fishermen who lived on the River in Shaoguan city.This paper uses qualitative method to study the process of resettlement of fishermen’s families and explores the impact of resettlement on fishermen’s families and the intergenerational differences of different family members.The result shows that the livelihood of fishermen’s family was greatly improved due to the resettlement project,but this resettlement brought obvious about generational differences:old male fishermen couldn’t adapt themselves to city life,they are still lonely engaged in fishing,while the old women lived with their children in the low-rent house and undertook the responsibility of housework activities and caring for the minors; young people quickly integrated themselves into the life of the cities,who could have more work opportunity and increased income.As for the minors,they have better education conditions and larger social network and more friends.
