Thai table tennis star Orawan "Thip" Paranang fires balls across the practice table that dominates the living room of her modest house on the edge of Bangkok.

The makeshift training setup is the final stage of a 17-year journey that has taken the left-hander from poverty in rural Thailand to the grand stage of the Olympics.

The 24-year-old, once told she was too short to play the game, secured her spot at the Tokyo Games with victory in the Southeast Asia regional qualifiers in Qatar in March.

After helping to support her family in Thailand with prize money since she was 15, she now stands on the threshold of the highest stage.

"When I passed that point (Olympic qualification), I felt like I finally managed to lift a heavy stone off my chest," Orawan told AFP.

"It was an indescribable feeling."

Her love of the game was sparked in her home district－deep in the rice fields of Ubon Ratchathani, a farming province on the border with Laos and Cambodia－when the 7-year-old Orawan saw older pupils winning prizes at school.

But as the fourth of five children born to poor farmer parents, getting even basic equipment such as bats was a struggle.

"My family didn't really have much money to support my pursuit of this sport. But they've always been supportive spiritually and mentally and let me do what I love," she said.

Orawan also faced a battle to secure her first coach, slogging away at drills over countless hours to prove her commitment.

Eventually the coach agreed to take on Orawan, pay for her kit and equipment, and she later enrolled at a specialist sports school in Bangkok.
