Take the K91 bus to Ximen Station, then walk 251 meters to Wulong潭 Park. (Note: "Wulong潭" is translated as "Wulong Spring" or "Five Dragons Spring" in some cases, but without context, I'll keep it as "Wulong潭 Park" to maintain accuracy.) For a more natural translation: Take the K91 bus to Ximen Station, then walk 251 meters to Five Dragons Spring Park.
