Who is "Gui" in the Cantonese proverb "Don't ask Gui"

This sentence is related to Ye, the governor of Guangdong and Guangxi in the early years of Xianfeng. There is the following statement:

1. When Ye was promoted from the Governor of Guangdong and Guangxi to the Governor of Guangdong, his official position was located in Yide Road, Guangzhou, the former site of the French church stone room. Bai Gui, a Manchu, succeeded him as governor-general, and his office was located at Ai Hui Road, the former site of the First Park. Because the governor and the governor's office are both located in Guangzhou, many things are decided by the governor, not by the governor.

Second, Ye and his father are superstitious about Fu Ying, and they should ask Fu Ying about everything, big or small. Ye built a Changchun Fairy Museum for his father and let him live in it. Lv Dongbin and Li Taibai are treasured in the museum. Even the military cardinals depend on Fu Ying for all their daily actions. When the British and French allied forces attacked Guangzhou, he also asked Fu that Fu Shuo would be fine in fifteen days, so his subordinates refused to let him defend himself many times. As a result, Guangzhou began to fall after fourteen days. Later, some people said that it was expensive for foreigners to buy your hand, but because of the secrecy of the matter, the world could not know the details.

3. "Mo Wen Agui" This Agui is the leader and organizer of 98 families with 38 surnames in Zhuji Township in the Southern Song Dynasty-Luo Gui.

Luo Guiqiu has made great contributions to the development of southern Xinjiang, and millions of descendants still remember the family history of your ancestors leading the people to move south more than 800 years ago.

In A.D. 1 132 (the first year of Shaoxing in the Southern Song Dynasty), with the approval of the government, Luo Guiqiu led a large-scale southward migration (the difficulty of escaping from Yan). The migration journey is thousands of miles, which takes two months and is full of hardships and dangers. People who walk by water cut bamboo rafts, untied the cable from the sand water on January 16th, went out to sea and drifted for two months, and arrived in Zhougang (Xinhui) on March 16th. Their descendants have survived more than 800 years in Song, Yuan, Ming, Qing and Republic of China, and their descendants are all over the Pearl River Delta and scattered in Guangdong, Guangxi and Hainan. In the process of continuous migration, future generations have developed a pioneering spirit and are not confined to their homes. The sentence "Don't ask Agui" was born and spread. "Don't ask Agui" contains the spirit of "overcoming autumn and forging ahead" during the great migration period. After the great migration, all generations of descendants were able to assess the situation, seize the opportunity, choose their place of residence and seek new development. After the Opium War, later generations went abroad and started businesses in Southeast Asia, Europe and America, with footprints all over the world. "Don't ask Aki, it must be kind!" Don't ask aki, it must be true! "
