They were stuck in thick snow in China, perched on a narrow mountain pass with strong winds blowing.
Even after rescue personnel arrived 45 minutes later, it was a struggle to get them moving again.
Some of the 100 or so Singaporean tourists stuck in three buses, which was on its way to Mount Wutai, were worried and called the Singapore embassy in Beijing.
But they did not panic.
“We were safe and informed of what was happening, so I wasn’t worried,” said a tourist, who wanted to be known only as Ms Keng.
Firefighters freed the buses by using a forklift to tow them out of the snow. No one was injured.
