Tsunami sparks search for son living in Japan
Thanks to real-time information, father monitors his whereabouts
BEIJING - Even before the waves stopped washing over the northeast coast of Japan, Li Guangqiang began the search for his son.
The professor knew that his son, a university student in Sendai, Japan, was living near the epicenter of the 9.0-magnitude earthquake that wreaked havoc on the coast last Friday, sparking a tsunami that swept far inland, devastating towns and villages.
