The world's longest undersea high-speed rail tunnel has just been fully bored through and it's bringing Hangzhou and Zhoushan closer than ever.  

The 76.4-km Ningbo–Zhoushan Railway, featuring the Jintang undersea tunnel, will cut travel time between Hangzhou and Zhoushan to just 1.5 hours by high-speed rail. Beach days just got a whole lot easier.
