How to hand wash clothes with powder detergent?

I believe that many of my friends have encountered the situation of washing clothes with washing powder in their lives, so how can I use washing powder to wash clothes thoroughly?

1. Prepare the water. 2 basins of water are required, 1 for washing and 1 for rinsing. If a sink is not available, a separate sink or bathtub can be used. Different z-colored clothes need different temperatures, white and light-colored clothes need hot water, and colored and dark-colored clothes need cooler water. Different temperatures can be adjusted each time the water is filled.
2. Add washing powder. Pour 1 or 2 tablespoons (depending on the size of the pot) in warm water. Mixing laundry detergent by hand helps to spread and foam.
3. Wet the clothes. Put dirty laundry in hot water. Soak for 10-15 minutes before rinsing off.
4. Start doing laundry. Mix the laundry with your hands and arms or stir with a stick, turning the laundry to let the dirt fall out.
5. Clean the dirtiest areas. Some items of clothing require careful handling. For example, socks, underwear and dirty work clothes require additional cleaning. These clothes should be rubbed by hand with some detergent.
6. Rinse for the first time. Drain the soap and dirt from the water and pour the clothes into the second basin of clean water. Rinse as much dirty water off your clothes as possible. If there is still a lot of detergent in the laundry, put it in clean water and rinse it again.
7. Remove excess water and then dry it.
