"Additionally, different from many people who lean toward prevailing job trends without careful consideration when looking for a job, these people actively choose their vocation, which means they are clear about what they entail.

"It's a positive circle. They have some foresight of the difficulties they will meet, but still choose to undertake the job, so they are more motivated to solve the problems when they arise," says Tang Sishi.

He says the conquering of one difficulty encourages these people to make further progress. "As a result, they often feel better compared with those who have no clear view of what job they want to do."
