This oil panting series is inspired by the ubiquitous existence of division and mergence. As an organic being, we experience dividing and merging constently on a microbiological level, meanwhile we also exert this phenomenon into abstract levels, such as culture, feature, matter, essentiality, etc. What are the origin, the process and the ending of these intangible dualities? By using primitive methods and basic elements to imitate and reemerge this process, I aim to interpret the fragment I obtain from nature.
