Based on the data from our corpus and survey, this paper aims to analyse a series of Chinese grammatical errors frequently made by Spanish students, in the light of theories of contrastive analysis and error analysis. We focus our analysis on the errors of six categories (polysemic correspondence, omission, order, collocation, classifier and deixis), and try to identify their possible causes. Lastly, we also offer some strategies in the hope of facilitating the Chinese learning in Spanish-speaking countries, as well as shedding some lights on the Chinese teaching and investigation.
