"GUANGZHOU, China — The rains brought torrents, pouring into basements and malls, the water swiftly rising a foot and a half.
The city of Dongguan, a manufacturing center here in the world’s most dynamic industrial region, was hit especially hard by the downpour in May 2014. More than 100 factories and shops were inundated. Water climbed knee-high in 20 minutes, wiping out inventory for dozens of businesses.
Next door in Guangzhou, an ancient, mammoth port city of 13 million, helicopters and a fleet of 80 boats had to be sent to rescue trapped residents. Tens of thousands lost their homes, and 53 square miles of nearby farmland were ruined. The cost of repairs topped $100 million.
Chen Rongbo, who lived in the city, saw the flood coming. He tried to scramble to safety on the second floor of his house, carrying his 6-year-old granddaughter. He slipped. The flood swept both of them away."
