We, humans, knows no limits. We can make anything possible whether it is constructing something under the sea or under the ground. China is all set to construct its first ever under the sea tunnel for high-speed trains. It has come up with this idea to cut the travel time from 1.5 hours to half an hour between Ningbo and Zhoushan. The tunnel under the sea will be 16.2 km long whereas the line will cover approx 70 km.
