A river is a linear natural waterway with frequent or intermittent water flow on the land surface.
Every river has a source and an estuary. The source of a river is the source of a river, some of which are springs, and some of which are lakes, swamps, or glaciers.
The water in the river is a combination of rainfall, melt water from the snow-capped mountains, and groundwater.
Therefore, the river refers to the freshwater waterway bucket back to the oak.
If all rivers flow with seawater, they are canals that connect the oceans, such as the Suez Canal, in Egypt. It connects the Atlantic Ocean to the Indian Ocean through the Mediterranean Sea and the Red Sea.
Panama Canal, in Panama. Connecting the Atlantic and Pacific oceans through the Caribbean Sea.

It does not flow to **, but only circulates in the oceans of the Earth.
The water in the oceans of the earth is flowing, called ocean currents. As shown in the figure below.
Ocean currents generally circulate between the polar regions, the equator, and high and low latitudes under the influence of the Earth's rotation and sea temperature. Fishing grounds are usually formed at the confluence of ocean currents with ocean currents.

Ocean currents can be divided into cold currents and warm currents according to their water temperature being lower or higher than the water temperature of the sea area through which they flow, the former coming from a low water temperature and the latter coming from a high water temperature. The horizontal velocity of surface currents ranges from a few centimeters to 300 centimeters of seconds, and the horizontal velocity of deep currents is less than 10 centimeters second. Lead has a very small direct current velocity, from a few centimeters a day to a few tens of centimeters per hour.
The direction of the current is the direction of the current, which is the opposite of the definition of the direction of the wind.
According to their causes, ocean currents can be roughly divided into the following categories:
1) Drift and crack current: the ocean current formed by the drag effect of the wind.
2) Geostrophic current: In an ocean that ignores turbulent friction, the stable current when the horizontal pressure gradient force and the horizontal geostrophic deflection force are balanced.
3) Current: While the ocean tides rise and fall, there is also a periodic horizontal flow, which is called a tidal current.
4) Compensating flow: The current formed by the seawater current of another sea area to supplement the seawater loss. There are horizontal compensation flow and lead straight compensation flow.
5) River discharge: Due to the flow of river runoff into the sea, the flow of seawater in the sea area near the mouth of the river is called river discharge.
6) Crack current: the current from the shore to the deep water when the waves propagate from the open sea to the coast to the wave fracture zone.
7) Shore Current: A current that moves parallel to the coast after the waves propagate from the open sea to the shore to the fracture zone.
These are the main currents of the ocean.

The Kuroshio Current is the second largest warm current in the world's oceans. The Kuroshio is like a great river in the ocean, 100,200 kilometres wide and 400,500 metres deep, with a flow rate of 3,400 kilometres per hour, which is 20 times the total flow of the world's rivers. It carries a huge amount of heat and flows from south to north day and night, bringing rain and a suitable climate to Japan, Korea and the coasts of China.

It's the Yangtze River.
The Yangtze River is the longest river in Asia, the third longest river in the world, the longest river in the world completely within the territory of a country, and the river with the largest runoff in China.
The Yangtze River is the most abundant river in China, with a total water resource of 961.6 billion cubic meters, accounting for about 36% of the country's total river runoff and 20 times that of the Yellow River. It ranks third in the world after the Amazon River and the Congo River (Zaire) in the equatorial rainforest.
Measured at the mouth of the Yangtze River, the maximum peak flood flow of the Yangtze River Datong Station is 92,600 cubic meters per second, the minimum dry water flow is 4,620 cubic meters per second, the maximum annual runoff is 1,360 billion cubic meters (1954), the minimum annual average flow is 676 billion cubic meters (1978), the average annual flow is 29,300 cubic meters per second, and the total annual runoff is 905.1 billion cubic meters.

It seems to be the Kuroshio (i.e., the Japanese warm current), I don't know if there is anything wrong. The Kuroshio Current (also known as the Japan Warm Current) is the second largest warm current in the world's oceans.
In the western part of the North Pacific Ocean, there is a strong ocean current like a huge river, rolling forward from south to north, flowing day and night, it is the Kuroshio. The Kuroshio Current, which originates from the North Equator, passes through the Philippines, clings to the eastern part of Taiwan, China, enters the East China Sea, passes through the Ryukyu Islands, flows along the southern part of the Japanese archipelago, and ends its journey in the waters near 142°E and 35°N. In the vicinity of the Ryukyu Islands, the Kuroshio branch out to the Yellow Sea and the Bohai Sea in China.
Qinhuangdao Port, located in the Bohai Sea, is not frozen in winter, which is affected by this warm current. Its main branch is eastward, traced all the way to 160° east longitude; There is also a group that first heads northeast, joins with the pro-tide (also known as the Kuril cold current) and then turns eastward. The total distance traveled by Kuroshio is 6000 km.

The Kuroshio Current is the second largest warm current in the world's oceans. Because the sea water looks blue like indigo, it is called the Kuroshio. In fact, its true colors are as innocent as usual. Due to the depth of the sea, the scattering of refractive light by water molecules, and the action of aquatic organisms such as algae, it looks like a black garment.

Among the world's rivers into the sea, it is located in South AmericaThe Amazon Hall Wheel RiverIt is the Yuxiao River with the largest flow, the widest basin area and the most tributaries in the world.
The Amazon River basin covers an area of 10,000 square kilometers, accounting for about 40% of the total area of the South American continent, and is the world's largest river with the largest flow and the widest basin area.
According to China's current strength, in fact, it already has the strength of the second largest power, according to official statistics, China's manufacturing capacity has surpassed that of the United States, but there can still be a big gap in cutting-edge. China is still controlled by others in many places, so it needs to continue to catch up, when China's cutting-edge technology and military strength become the dominant ability in the region, China is a real power... Just like the United States during the First World War, around 1910 the total manufacturing and market volume has surpassed Britain, but at that time the international community still considered the British style of the first power, World War I to World War II, the United States seized the powerful international situation, waiting for the two blocs to fight, Britain, France-Germany and Italy, and finally clean up the mess by themselves, become a real and nominal superpower, is also well deserved... >>>More
The lightning sparked the second-largest wildfire in California's history, killing at least six people and injuring 43 firefighters and civilians.
According to the September 3** road,Today's population growth has made sand the second most important natural resource after waterBillions of tonnes of sand are being used around the world. In 2012 alone, the sand used globally was able to build concrete walls 27 meters high and 27 meters wide along the equator, according to a United Nations report. We don't need to go to the beach to play with sandcastles, our city is essentially a giant sandcastle made of sand. >>>More
