Where is Jianghu is a book about Taiwan's agricultural ecology, referring to economic research such as agricultural self-sufficiency and agricultural product sales, but local factional issues that farmers will encounter. The obstacles usually encountered in agriculture in Taiwan are not financial difficulties, but the control of local factions, and the irrational implementation of government policies. At the beginning, it mainly discussed the disadvantages of agricultural policy in the past 50 years.

First of all, the article mentioned policies such as rent reduction in 375, release of public land, farmer's own land, and rezoning of farmland. Just like the context of national development, if the government is to develop industry and commerce, it will sacrifice the original agriculture. At that time, the approach adopted was to support the industry by using agriculture to reduce the price of rice to enable the first-tier industry to surpass. Let industry and commerce develop in this environment, transform from light industry to heavy industry, and then transform from heavy industry to science park. Later development can be imagined, it is the technology island that is now commanded by semiconductors.

However, the development of industry and commerce is of course beneficial to the development of the country, but the right to survival of the farmer children will be further compressed. Because of the low rice price, the farmer children will only receive a meager salary, plus themselves Because the government's taxes have not been reduced or exempted in the general environment, many people have abandoned farming and doing business, making the people who undertake agriculture gradually aging.

In addition, heavy industry often brings low pollution. Wastewater and waste soil are discharged to farmland, which is to contaminate the entire farmland, making it impossible to cultivate the existing land, which can only be acquired by the government as industrial land or residential land. But this matter is extremely unreasonable in terms of industry sustainability.

Followed by the underworld's involvement in agriculture, there are usually four ways to use it for farmland. The first step is to rent or purchase idle or semi-idle farmland, and then dig out the topsoil and sell it to a familiar material dealer as the first gray income. The next step is to dig the sand and gravel below, and sell the sand to the gravel yard, becoming the second gray income. Another is to let waste disposal operators fill up with waste soil or waste metal materials from other places to earn a third gray income. The last is to resell the useless farmland to the builder and earn the last income.

Moreover, it is not only the destruction of agricultural land that is converted into construction land, but the engineering bidding is also a major scourge of local ecology. Because farmland damage can be exchanged for sand and gravel, the construction is to use these sand and gravel to build parking lots and ports. Therefore, wild streams that should not be cemented will be grouted into cement trenches. This is often a great harm to the local soil and water conservation, but before the local factions, no residents would have opinions, and most of them dared not be angry.

Finally, from this book, we can know that agriculture is an industry that has been forgotten by the public, and it is also controlled by the peasant association system. So how to improve these conditions requires the joint consultation of the central ministries and local forces, otherwise agriculture will always be a frontier area of ​​industry.
