Subway line's ok, they say

Guangzhou - Some doubts about the safety of a certain part of the city's northern subway extension that were made public in September have now been laid to rest - maybe.

It all has to do with claims of substandard concrete work in a passage in the northern extension of Subway Line 3, which were made over the Internet in mid-September.

The whistleblower was Zhong Jizhang, an engineer at the Guangzhou Huijian Center of Engineering Quality and Safety Monitoring, who claimed there had been a cover-up, which triggered worries about the safety of the city's subway projects.
