income
收 centers on receiving something that comes in, especially money or earnings. Its core idea is income or taking in what is due.
收 is the traditional form of modern 収. It combines 丩 (likely a phonetic component) with 攵 (a hand holding a stick, suggesting an action), together conveying the idea of collecting or receiving. The exact origin of 丩 is uncertain, but the character is historically associated with gathering or income.
The left side 丩 looks like a twisted cord or a container, and the right side 攵 is a hand holding something. Imagine a hand pulling a cord to draw in a bag of money, representing income coming in.
For シュウ, picture a shoe (シュウ) being used to collect coins: you take off your shoe and use it to gather your income. Shoe -> シュウ, and the hand (攵) is pulling the cord (丩) to bring the money in.
