price of Shanghai Huangpu river sightseeing cruise

Hi! i have read in tripadvisor that the huangpu river cruise would cost around cny120 per person, while in this site it is stated that it would cost only around 12cny. can you tell me if there's a mistake here in the stated price; is this the same ferry sightseeing river cruise that these websites are referring to; or is there another ferry sightseeing line that cost only 12cny. For clarification please. Much thanks!
