Yesterday I bought the wrong ticket. The staff came over three times and said that it was very difficult for you to climb the snow-capped mountain with your big luggage and baby. I only understood it for the third time, and then refunded the ticket for me. Today I want to buy a bus ticket. The driver also repeatedly reminded you to use the mountaineering train ticket, and it was several times before I understood it. The landlord of the place to stay is not there. There are three Americans living here, but Americans don't say the country, they directly say the place name.
