What does the word "big policy" mean? I believe that many friends can't say it clearly.
This is also understandable. Because, "big policy" itself is not a fixed word. Literally, it's a "big plan," but there doesn't seem to be such a usage.

As a word, "big policy" is already a bit difficult to figure out; as a place name, its meaning is even more confusing. In the territory of Gaogezhuang Town, Laiyang City, Yantai, there are three villages with the name of "Da Ce", namely East Da Ce, West Da Ce and Qian Da Ce.
How did these place names come about? The interpretation of Laiyang geographical name data is also suspicious. Regarding the origin of Dong Da Ce, one theory is that the ancestors of the village once used clever tricks to escape a disaster, which is called "Da Ce Yuan", hence the name; there is also a theory that there was a temple near this place in ancient times, and Da Ce evolved from the Great Temple. Relatively speaking, the latter statement may make more sense. As for the West Strategy and the Former Strategy, the explanation of the village chronicle is quite simple, simply saying that there was an East Strategy first, and the two villages that were established subsequently were named according to the location of the Strategy.
Interestingly, these villages not only have individual names, but also have surnames. Among them, XiDace Village and former Dace Village have many People with the surname of Gai, while the surname of DongDace Village is more special, which is a village where people with sticky surnames live together.
In the scope of the Jiaodong Peninsula, although the Gai surname is not a big surname overall, it is a Wang family in Laiyang Nanxiang. The Genealogy of the Gai Clan records that the ancestral home of the Gai Clan in Laiyang is the Fengtou Village of Jiang Yan Town. Xidize Village and Former Dace are not far from Fengtou Village, and it is not surprising that there are branches of the Gai surname.
The Laiyang County Chronicle, which was revised in the 1930s, also said when introducing the surname of the county: "Gaishi, the clan of Taishoutong, the fengtou village of the third district of Shiju, the villages of Jiang yan, Anli, Senbuzhuang, Gaijiazhuangzi, Shangkuan, and Dace." ”
Although Gai is a characteristic surname, it is always more common. In contrast, dongda ce's sticky surname is more legendary, and I believe that many friends from other places may not have touched this surname before.
In fact, as far as the whole country is concerned, sticky is also a rare surname, in addition to the large-scale distribution in Fujian, Laiyang, the village of Dongdace, is also a well-known sticky surname settlement village.
Although the surname is peculiar, because of the genealogical inheritance, the history of people with the surname of DongDa ce is still relatively clear, and the author has had the privilege of seeing this genealogy in Dong Da Ce Village. According to genealogical records, their ancestors were the Jin Dynasty general Sticky Han (完燕宗汉). One of its descendants took the sticky character as a surname and lived in Fujian in the Yuan Dynasty. At the beginning of the Ming Dynasty, from south to north, he migrated to Dongdace Village in Laiyang County, the capital of Dengzhou, to settle down. The genealogy also summarizes a poem for this purpose, which reads: "Ming Dynasty Hongwu came to Changyang, the origin of Yongjin Hundred Generations; faithful benevolence, righteousness, virtue and fulu, wealth and glory." ”
