What later attracted Moser to study Chinese in China were some tapes of "xiangsheng", or crosstalk, a kind of Chinese comic dialog. He listened to the tapes with growing fascination. In 1991, Moser came to China's Peking University (PKU) as a visiting scholar to collect materials for his Master's thesis on "xiangsheng".
Life at PKU was very smooth for Moser, where he was taught by Professor Wang Jingshou, a renowned "xiangsheng" expert, who later introduced many popular "xiangsheng" performers to this foreign student. In Wang's opinion, Moser is gifted in performing, and thus he recommended him to famous crosstalk performer Ding Guangquan, whereupon Moser began to study with him. From then on, Moser followed Ding to participate in many performances around China, and started to be known by Chinese audiences.
