Migrant workers have many other job options after retirement besides hard labor. Although migrant workers may have limited skills and education, they can still find work that suits them in a number of ways.

First of all, migrant workers can choose to continue working in agriculture in rural areas. Although agricultural work is hard, it is a familiar and skilled way for experienced migrant workers to work. They can continue to engage in agriculture by growing vegetables, fruits or raising livestock, etc.

Secondly, migrant workers may consider taking up agriculture-related jobs in the cities. For example, they can find jobs in the city's farmers' markets, agricultural science and technology parks, or agribusinesses. These organizations usually need people with agricultural experience to help them with marketing, technical support or agricultural management.

Also, migrant workers can choose to work in jobs related to industries such as construction, renovation, cleaning or gardening. Many cities are in need of laborers to carry out construction work, house maintenance, cleaning services or horticultural maintenance. Migrant workers can utilize their physical strength and work experience to find suitable employment opportunities in these fields.

In addition, migrant workers may consider receiving some vocational training to upgrade their skills and knowledge. For example, they can learn computer skills, automobile maintenance, chef skills or skills related to the service industry so as to find better employment opportunities in these fields.

Finally, migrant workers can also choose to start their own businesses or become self-employed. They can utilize their experience and skills to start small agricultural plantations, catering outlets, cleaning service companies or small construction companies. Entrepreneurship not only brings financial gains, but also increases the social status and autonomy of migrant workers.

Overall, migrant workers have many job options after retirement. Apart from continuing to work in agriculture, they can also take up agriculture-related jobs in the cities or choose to work in jobs related to industries such as construction, renovation, cleaning or gardening.

In addition, they can upgrade their skills through vocational training, or choose to start their own business or become self-employed. Importantly, migrant workers should actively look for jobs that suit them and continuously upgrade their abilities and qualities to meet the needs of social development.
