游 for swimming in water. 遊 for travelling and touring.
斿 pictured a banner rippling on its pole with a child beneath it. Add water 氵 and the rippling moves into the river: 游 is motion that flows — a swimmer through water, a traveler through landscapes.
游 carries both of China's favorite freedoms: 游泳 swimming and 旅游 travel. 西游记 'Journey to the West' — the Monkey King's road trip — is literally 'Westward 游 Record'. To 游 is to move the way water does: unhurried, curious, everywhere.
A banner 斿 rippling — now let it ripple through water 氵: SWIMMING.
游客 'traveler-guest' is the word every scenic spot in China greets you with; on a busy holiday, 游客 outnumber locals ten to one at West Lake.
