Giggling kids raced cheerfully along the lakeside beach,     3     their parents enjoying the shady picnic areas under the trees along the shore. “It’s a great day out,” said Paul Lin, co-founder for Castaic’s own Dragon Eyes team.

Dragonboat racing has been going on for thousands of years in China,     4     (initial) in honor of the Chinese water dragon deity(神)in an effort to call down rain and avoid     5     (fortune) and disaster.

In the race, a drummer     6     (use) a large traditional wooden drum to keep the paddlers on beat, while a steersman in the back keeps them in their lane.

Lin said a friend got him    7     (involve) in dragon boat racing over a decade ago. In 2018, they decided to host their own festival. “There’s     8     really special to be learned from our dragon boat motto: ‘One Boat, One Beat ’,” he said. “Paddlers come from all walks of life and that kind of     9     (close) with people is nowhere else to be seen.”

“We really want to help expand awareness and grow the sport,” Lin said. “We’re hoping one day it’ll become     10     Olympic sport.”
