Narrative 5: Comparison with the plans by Japanese aggressor government during 1939-1940 《DA TIAN JIN DU SHI JI HUA DA GANG TU》《TIAN JIN DU SHI JI HUA DA GANG》《TANG GU DU SHI JI HUA YAO TU》
The later three narratives are about comparing the Liang Zhang Plan to other plans made in similar time period.
The Vision of Japanese Government was to build Tianjin into a strategic port in the north China. From the plan, we can see the plan emphasized on the canal system and expand the city toward East side all the way to the coastal area. They planned to dig another canal in between the Jinzhong River and Hai River. Along both sides of this canal, industrial factories were planned in linear arrangement. Also there is the flight field, which indicate the demand relate to war. Also the residential area is divided into different hierarchy, which was probably to distinguish the Japanese residents as the ruler class and Chinese residents as the ruled class. And they decided to develop the Tanggu port on the east side near the coastal line, due to the reason that Tianjin always had the problem of frozen river during winter, so they needed the port more close to the sea in order to guarantee the transportation during entire year.
The maps conveyed the mindset of such planning, which is to turn the occupied port into a military base and transport hub, also into the base area for further aggression. So the difference of these two plans is quite clear after understanding the different starting points of the planner. For example, the functional zoning in the Liang Zhang Plan was to improve the living environment and clearer administration, while in the Japanese plan, the functional zoning was to increase armament production and transport plundered resources.
