This resolution is Congress telling the President what it thinks he should focus on when he next meets with China's leader, Xi Jinping — specifically, pushing for the release of five people currently detained in China: two pastors, one pastor's wife, a doctor, and a media entrepreneur. It also asks the President to demand proof that these people are alive and being treated properly, that they can talk to lawyers and family, and that they get medical care if needed. Importantly, this doesn't force the President to do anything or change any law — it's a formal statement of opinion from the House expressing support for these detainees and for religious and political freedom more broadly, with no binding requirements attached.
