It's harder than you think because the same word can mean tons of things...
ie: to type 走吧 is just in the chinese keyboard "zouba"
but zou can mean
走, 奏, 鄒, 揍, 驟, 謅, 諏, 陬, 棷, 棸 ... list goes on and on.
and ba can mean
八, 拔, 把, 爸, 吧, 芭, .... etc, etc.
So using simple numbers like 98 saves lots of time.
