rub, massage, shampoo, debate vigorously, train, coach, worry, get in trouble
揉 centers on applying pressure with the hands to work something: rubbing, massaging, or kneading. The extended senses of vigorous debate, training, and worry all grow from the idea of working something over repeatedly until it softens or changes.
揉 combines 扌 (hand) with 柔 (soft, gentle), suggesting the action of softening or working something by hand. The phonetic contribution from 柔 is likely, but the exact historical development is uncertain.
A hand 扌 works on something soft 柔: imagine kneading dough or massaging shoulders until they become pliable. That repeated working motion extends to training, debating, and even worrying a problem.
For ジュウ, picture a jeweler gently rubbing a soft gem: jew -> ジュウ, and the hand 扌 massages the soft 柔 stone.
