Security beefed up nationwide

Greater police visibility, rigorous inspections seen as way to relieve public anxiety

Experts said on Wednesday that residents' anxieties about terrorism can be reduced by strengthening security in crowded places, but the key is persistence.

Armed police patrols were enhanced nationwide after a violent incident on Tuesday, when six people were injured in a knife attack in Guangzhou Railway Station. It was the third attack targeting civilians at a railway station in just two months.
