In 2009, "Shanyuhai" began to explore the domestic migrant pension model. Through self-construction, self-management, owner trusteeship, cooperative joining, etc., it is the first to advocate the migratory bird pension model in China, and organically combine the needs of finance, real estate, pension and leisure vacation. By the end of 20 12, "Shanyuhai" has developed into a well-known domestic membership-based chain brand focusing on ecological living and supporting the elderly by migratory birds.

Migratory bird-style pension is a special kind of pension life, which is like a bird choosing different regional environment to support the elderly with climate change, and it is a kind of pension method with a certain economic foundation. Migratory birds provide for the elderly by choosing different places to travel with the change of seasons. This way of providing for the aged in institutions such as nursing homes and apartments for the aged in different places integrates health services, tourism and leisure, culture and entertainment, and is a healthy and happy way to enjoy life and provide for the aged.

Once this "migratory bird" pension model was introduced, it was very popular with the elderly. Many pension institutions are exploring the "migratory bird" pension model, and the nationwide networking or even "transnational interaction" of nursing homes may become the future trend.
