The rice is too soft to steam, you can not disconnect the power to uncover the pot and steam for a while, so that the excess water evaporates.
The best measure to remedy this is to use the vapor evaporation method to reduce the water in the rice. Specific method is to open the lid of the pot, while the heat will turn the rice fluffy, so that the air and rice in full contact with the air for about ten minutes, so that the water evaporates, and then cover the lid to continue to steam, repeated many times.

Notes on steaming rice
The first big secret--washing rice: wash the rice must not be more than 3 times, if more than 3 times, the rice will lose a lot of nutrients. If you wash the rice more than 3 times, the nutrients in the rice will be lost, and the flavor of the steamed rice will be reduced. Remember to wash the rice not more than 3 times.
The second secret - soak the rice: first soak the rice in cold water for half an hour, so that the rice grains can fully absorb the water. This way the steamed rice will be full of grains.
The third secret - the ratio of rice and water: when steaming rice, the ratio of rice and water should be 1:1.2. There is a particularly simple way to measure the amount of water, with the index finger into the rice water, the water should not exceed the first joint of the index finger.
The fourth secret - aroma: If the rice at home is already stale, it's okay, stale rice can also be steamed with the flavor of new rice. That is, after the first three processes, add a small amount of refined salt or peanut oil to the pot. Remember that peanut oil must be boiled and cooled, just add a little to the pot.
