大连自古以来就是辽东半岛和山东半岛的桥梁和纽带,至今已有5000年的历史。两地之间最早的交流始于港口,随着社会的发展和航海工具的不断改进,交流不断扩大,包括国家的统一、民族的融合、文化的传播等,都作出了历史的贡献。 Dalian has been a bridge and link between the Liaodong Peninsula and Shandong Peninsula since ancient times, and it has a history of 5,000 years. The earliest exchange between the two places began in the port. With the development of society and the continuous improvement of maritime tools, exchanges have expanded continuously, including the unification of the country, the integration of ethnic groups, and the spread of culture. All these made historic contributions.
