官渡

官 = 㠯 + 宀 : Mnemonic symbol: to symbolize the bureaucracy involved in every governmental system I'll use a folder.

官 = 㠯 + 宀 : Gitta Giraffe just graduated from anthill, and standing in front of it, still wearing her graduation cap, she's ready to assume her post as government official. She already has a folder under each arm and is wearing big safety glasses (be safe at work!).

渡 = 度 + 氵 : Doggy Dog (du) is going to a party in the space station's bathroom (Ø4). To get there he'll have to take the ferry (渡), but he's worried that his drink will be cold by the time he arrives. He's constantly measuring the temperature of his bottle of water (氵) using a thermometer (度).
