Over three million times of training on vocational skills are scheduled to be carried out in East China's Shandong province from 2019 to 2021, according to the recently released plans for upgrading the vocational skills in the province.

"By 2021, vocational skill-armed labor force will account for at least one quarter of the labor force in Shandong," Xia Luqing, deputy head of the Human Resources and Social Security Department of Shandong province, said at a news conference held in Jinan on Thursday.

Workers at enterprises, college students, ex-servicemen, rural migrant workers, junior and high middle school students not attending colleges, professional farmers and poverty-stricken people are the major groups that will get trained.

In addition to training classes at places such as enterprises and schools, classes will be available online including through smart phone apps and WeChat public accounts to meet demands of as many people as possible.
