Grand Fishing Port
Harbour is a building chain in Total War: Three Kingdoms. Its main branch produces a small amount of food as well as steady income from commerce. The first alternative branch trades in some food for extra income in the entire commandery. The final branch produces no food but provides even larger amounts of income, as well as providing trade influence and a faction-wide income boost for spices. All three branches give a small reduction in construction cost for Agriculture buildings.
Building Chain[]

Abandoned Jetties
Abandoned Jetties (level 0)[]
The people here keep to themselves; untouched and unchecked by the guiding hand of government. The people here are inward looking and able to operate outside of government influence, which has the disadvantage of not knowing what threats lie in wait beyond their boundaries. Establishing an authoritative presence here would do much for the wellbeing of the people, providing both them and the country with additional prosperity.

Pier
Pier (level 2)[]
To extend trade, extend its architecture. A jetty extends the reach of the village’s existing pier, reaching out past the shallows of the coast over deeper waters, to enable fishing without the need for a boat. It also has a greater space for incoming or outgoing boats used for trading and transport, and increases commerce in a town. The jetty can then be developed into a commercial or fishing harbour, depending on which one yields the greater profit.

Fish Trader
Fish Trader (level 3A)[]
A trader established at the dock has an intimate knowledge of the most profitable hauls. A trader increases the amount of food and a small increase in income generated from commerce. A fish trader can buy their wares straight from the fishermen, or actually catch the fish themselves, but their speciality lies in selling fish to villagers or to third parties. The trader has an advantage over fishermen in that he can be in one spot permanently, has the accommodation to store the fish for selling, and can choose to buy his stock from all the fishermen in a village.

Fishing Port
Fishing Port (level 4A)[]
More space for fishing boats to dock increases the quantity of goods that can be brought ashore. A fishing port accommodates fishermen and their boats. Here, a number of fishing boats can dock directly and unload their wares, to be recorded and sold to fish traders occupying the outskirts of a port. Payment can be taken immediately or decided once the fishermen have made their catches for the day, or until the profits have been taken into account. In this way, a relationship between both fishermen and traders is established for mutual profit.

Grand Fishing Port
Grand Fishing Port (level 5A)[]
A lively and profitable fishing hub which grows with each new haul. China’s proud fishing tradition is realised through a grand fishing port. The catches in this district have been plentiful, the fish market is heaving with fresh fish and bustling with customers and the fresh sea breeze that wafts in over the trade is both refreshing and exciting. The revenue from developing local fishing businesses has been wisely reinvested, and the food and income generated provides a sturdy and reliable source of money.

Harbour Trader
Harbour Trader (level 3B)[]
With the development of the settlement comes greater opportunity. Development of a jetty into a harbour trader increases commerce into a district at the expense of specialisation. Customers, merchants and visitors can anchor and moor their boats or ships in the harbour, either to sell to merchants, purchase goods or both. Much trade comes via the East and South China Sea routes, from countries as far flung as Tianzhu and Daqir. China's exotic goods are well received in these places, and in high demand.

Trading Port
Trading Port (level 4B)[]
A port specialising in trade can bend all resources towards it. A port, specially developed towards trade, both external and internal, greatly increases the rate of commerce within a region. Ships and boats who do business along the East and South China Sea routes bring in and take out wares to Tianzhu and Daqin, exporting many of China's unique goods, such as silk and lacquerware, as well as resources that are scarce elsewhere, such as salt and iron. The opened trade routes bring in new ideas and experiences as well as commerce, and as such are just as vital to China’s growth.

Grand Trading Port
Grand Trading Post (level 5B)[]
Trade flows as endlessly as the sea on which it arrives. A grand trading port accommodates many ships, either leaving or returning from trade in the South and East China Seas. Like the tides, for every shipment and crew that arrives there are those preparing to leave, and the port is noisy with activity as a result; it is loaded with luxuries such as lacquerware and silks, livestock of cattle, pigs and sheep, and foodstuffs like grain, dried fish and spices. The goods are matched in variety by the people who profit from the port, such as sailors, fishermen and market traders.

Spice Trading Port
Spice Trading Port (level 5C)[]
There are as many opportunities as there are flavours. The demand for spices is high, and becoming more and more popular with people as a way of increasing the complexity of their dishes. China produces and exports its own spices, but many are imported from Tianzhu as well, and a spice trading port can take advantage of the South and East China sea routes to increase commerce within a region. This lucrative trade partnership expands China’s standing in the eyes of the world and brings many new opportunities for commerce within and without.
