是中国首批沿海开放城市，位于河北省东北部，南临渤海，北依燕山，东接辽宁，西接京津。 是京津冀辐射东北的节点城市，中国最大铝制品生产加工基地，被誉为“车轮制造之都”。 同时也是国家历史文化名城，是中国唯一一个因皇帝帝号而得名的城市。
是秦皇岛市四个市辖区之一，因著名海滨景区、世界著名观鸟圣地北戴河而得名， 北邻抚宁区，东邻海港区，南依北戴河新区。北戴河区是中国规模最大的休养疗养基地和会议培训中心， 它犹如一颗璀璨明珠镶嵌在渤海湾北岸中部。
山海关古称榆关，也作渝关，又名临闾关，因其北倚燕山，南连渤海，故得名山海关，有“天下第一关”之称。 2001年，山海关被列为国家历史文化名城旅游景区，“老龙头”、“孟姜女庙”、“角山”、 “天下第一关”等六大风景区对中外游客开放，闻名国内外。
始建于1923年4月，坐落于辽宁沈阳，是国家首批“211工程” 和 “985工程”重点建设高校。有177个学科有权招收硕士研究生， 108个学科有权招收博士研究生；有17个博士后流动站；3个一级学科国家重点学科； 4个二级学科国家重点学科；1个国家重点学科。
秦皇岛位于渤海岸边，餐饮以海味食品为主要特色。 招牌海鲜菜有蟹黄鱼米、清蒸加级鱼、三椒虾丝、炸溜子蟹、绣球海贝、酱爆皮皮虾、红焖栗子鱼等。 另外，秦皇岛还有许多特色小吃：回记绿豆糕、杨长子火腿肠、麻酱烧饼、桲叶饼、昌黎赵家馆饺子等。
