《The form of protection》 is a book that introduces various lids with different shapes and textures collected by the author’s mother. To the author, lids are more than just objects that keep dust out of food; they symbolize the mother’s desire to protect her family, presented in a tangible form. Each lid is numbered as if it were a valuable item in a collection, and listed under the title ‘Form of protection’. These ‘Form of protection’ are carefully preserved under the ‘lid’ of the book.
