I recommend you do black line drawings and include Chinese characters. Some of our complex care seniors, including fairly high-functioning Cantonese-speaking ones, found this too hard to follow and most could not recognize the drawings for what they were, which are very cute but also more difficult for older adults with visual impairments to recognize. Thanks for offering this fun option, though.
