In his visit to local villages in Simao City, Hu questioned villagers on issues of family income, power supply, drinking water, schooling, and medical services.

He called on a service center for poor urbanites and a help center for migrant workers from the countryside in Kunming, the provincial capital. He urged trade unions to help protect the rights of migrant workers.

The places Hu visited included a village of the Dai People, where villagers have improved their income through hard work, as well as a village of Jinuo People, a small ethnic group.

During his stay in these two ethnic villages, Hu greeted medical workers to celebrate the International Nurse Day on May 12.

Hu, who is also the Chairman of the Central Military Commission, had a meeting with senior Army officers from the barracks of the Chinese People's Liberation Army (PLA) in Kunming.
