During the Spring and Autumn period, there was a man named Lord Mengchang in the State of Qi. He was fond of befriending literati and chivalrous individuals, often inviting them to reside in his home for discussions on state affairs. Among them was a man named Feng Xuan, who often stayed for extended periods but did nothing. Although Lord Mengchang found this peculiar, being a hospitable host, he continued to entertain Feng Xuan warmly.

On one occasion, Feng Xuan went to Xue, a territory of Lord Mengchang, to collect debts. However, instead of collecting, he burned all the debt bonds. The people of Xue believed this was an act of benevolence from Lord Mengchang and were filled with gratitude. Later, when Lord Mengchang was dismissed from his prime minister position by King Qi and moved to Xue, he received a warm welcome from its people. Only then did Lord Mengchang truly recognize Feng Xuan's talent.

It was at this point that the usually quiet Feng Xuan told Lord Mengchang: 'A clever rabbit usually has three burrows to escape a hunter's pursuit in an emergency and avoid death. But you currently only have one hiding place, so you cannot sleep soundly yet. I am willing to arrange two more secure hiding places for you.' So, Feng Xuan went to meet King Hui of Liang. He told King Hui that if he could invite Lord Mengchang to govern his state, Liang would surely become stronger. King Hui then sent messengers to invite Lord Mengchang to Liang, intending to offer him an important governmental position. However, Feng Xuan repeatedly advised Lord Mengchang not to accept, even after messengers from Liang came three times.

When the news of Liang's invitation spread to King Qi, King Qi became anxious and promptly sent for Lord Mengchang to return and resume his role as prime minister in Qi. Feng Xuan then suggested that Lord Mengchang request from King Qi the ancestral sacrificial vessels of Qi, and that these be placed in Xue, along with the construction of a temple there to ensure Xue's security. After the temple was built, Feng Xuan told Lord Mengchang: 'Now your three secure resting places are all established. From now on, you can elevate your pillow and sleep soundly.'
