Warning. I'm wearing my pimp hat askew. I recently received a shipment of Xiaguan 5x100g 'horseback tuocha' from Gordon at Dragon Tea House on Ebay. It has scenes printed on the unique cylindrical cardboard drawstring wrapper of horses with backpacks,courtyard stacked with tuos,mysterious pyramid symbol. I resolved the horseback and tea characters stamped all over the packaging. Try as I might I could not determine what should have been the tuo character commonly used. Gordon sent me the tuo character which means carry on back or piggyback which isn't on Zhongwen or in my printed dictionary but on Unihan. Damn confusing PinYin. These are the characters for horseback tuo:
