I was only a freshman then, and you can probably imagine the level of my Chinese. At the time, the school also lacked good conversation texts. When I first got to those Tungkan villages, I couldn't even say chopsticks. With my first stay of 45 days, my Mandarin and Kansu dialect made great bursts of improvement.
想想那時我才一年級，中文水平可想而知，當時學校也缺乏好的口語教科書，剛到東幹時，我連筷子都不會說，第一次在那兒住了四十五天，我的漢語和甘肅土話就都突飛猛進。
