作为社会主义道路的首位实践者，苏联在国际共产主义运动及继发社会主义国家的建设和发展中，有着 “老大哥”的角色担当。其发展历程、模式与前景等，对中国共产党而言，无疑为可参照的俱佳样板。新中国成立前，东北旅顺口区，由于独特的地理位置和地缘政治结构，已被纳入苏联管辖之下。苏联驻军于旅顺大连，为中共在旅大地区获得实质性地方政权提供了可能，也使得旅大民众与苏联人直接地进行接触，这一地区的“学苏友苏”活动因此比较复杂。 具体地讲，出于中苏双方共同需要，1945～1949年中共在旅顺开展了一系列塑造“苏联老大哥”光辉形象的宣传活动。通过梳理该时期旅顺口区相关档案，可以清楚地了解到宣传塑造的动员举措及动员逻辑。其以中苏友好协会为载体，组建宣传队和文艺工作队，依托政治宣讲、文娱活动、技术借鉴和情感交互等手段，旨在为旅顺区民众呈现出具像鲜活的“苏联老大哥”。从宣传成效看，一定程度上达到了预期目的；囿于中苏博弈、战时环境、民众实际观感及宣传者水平有限等因素，宣传塑造问题有待深究。

Recognized as the first socialist country in the world, the Soviet Union played the role of "big brother" to other socialist countries, as they drew lessons from the Soviet Union’s path, progress and prospects of development. Before the People’s Republic of China was founded in 1949, Lüshun in northeastern China was once occupied by the Soviet Union due to its unique geographic location and geopolitical structure. With the Soviet troops stationed in the Lüshun-Dalian area, the Communist Party of China (CPC) began to gain substantial political powers over the region, and the local Chinese people started to have direct encounter with their Soviet counterparts, thus breeding ground for campaigns to “learn from and befriend the Soviet Union.” Driven by the common needs of China and the Soviet Union, the CPC carried out a series of publicity campaigns to shape the image of the Soviet Union as the “Big Brother” from 1945 to 1949. Relevant historical documents on the Lüshunkou District have shown how the CPC advocated for the formation of publicity groups as well as literary and artistic groups, underpinned by the Sino-Soviet Friendship Association, to create a concrete and vivid “big brother” image of the Soviet Union through political preaching, recreational activities, learning Soviet technology, emotional interactions and more. Such efforts had, to a certain extent, achieved desired publicity results. Nevertheless, the gaming between China and the Soviet Union, public acceptance during wartime, and the ability of personnel acted as factors leading to several problems that need to be investigated.
