While her physical handicap brought her enormous difficulties, she overcame the challenges and typed slowly with her feet. It took her about four years to finish her book.

"I never felt tired during the process," she said. "I really love writing and my dream gave me great power."

"I look forward to our following journey. I have never seen the sea before and my husband specifically chose the route along the sea."

Bouyinhshig said he hoped the couple's trip would bring more precious experiences, which could be used as an inspiration for Zhao to write in the future.

"I know there must be lots of difficulties during the trip," he said.

"I have been well prepared and I want to take her to see the real outside world."
