A three-day ticket from Guangzhou Metro to 50 yuan is an economical choice. The fare is 50 yuan, valid for 72 hours, during which you can take the Guangzhou Metro for unlimited times (except trams and intercity railway lines). Compared with purchasing a one-day ticket separately, a three-day ticket has a more favorable price and a longer use time, which provides more flexibility and convenience for tourists. For tourists who come to Guangzhou, if you buy a three-day ticket, you can travel all over Guangzhou in three days, which is convenient for punching in multiple scenic spots, saving time and money and avoiding frequent ticket purchase.
