The car stopped in the "Huangdao" service area. After getting off the bus, I saw the sign and thought I was dazzled. Even the sailing boat that made the landmark was written "Qingdao". How did the service area become "Huangdao"? Ask the driver to know that the original "Huangdao" in Shandong Province administrative area division, belongs to the "urban jurisdiction" level, subordinate to Qingdao City. The reason why this island is named because Huangdao is located in the north of Huanglu Mountain, surrounded by the sea, the soil layer is thin and brine-bearing, the earth and stone are yellow, which is secondly different from the east bank of "Qingdao". Huangdao also has a rich human history, more famous are: Qi Great Wall site, Song Jintang Island Bay sea war site, Maqi Canal site, Baiyun Temple site, four-eye well, Yangwuhou ancient tomb burial, etc. In addition to tourism, several large industrial groups are also the national people are like the brand. For example: Haier Group, Hisense Group, Au Kema Group and so on. Therefore, tourism is also a way to long-term knowledge, go out and see, than holding a book to remember the geography of the intuitive impression 10,000 times, wow.
