Guanghan

Head to Guanghan to visit the amazing museum at Sanxingdui (三星堆), where they discovered the first evidence in millenia that the Bashu empire really did exist. You need to see it up close to understand, and you will not the disappointed by the thorough, well-explained museum or the excellent local transportation there (buses head there from downtown Guanghan every hour, and the conductor on hour bus was endlessly helpful, even with my terrible Mandarin).
