张悦然在小说中喜欢把爱情描写到极致,惯于书写决绝式的自我牺牲,甚至是自虐式、自我毁灭的爱情模式。《誓鸟》沿袭了张悦然情爱叙事的模式,所不同的是爱发生了转移、变异,对爱的痴迷与疯狂转变到对爱的附属物或者爱的凭借上。情爱的转移导致情与爱的悖谬,导致情感的放逐与背离。无性之爱、乱伦之爱、同性之爱都缺乏滋生爱情的土壤,缺乏合理性存在,决定了爱的徒劳与虚无,注定了悲剧性命运。 Zhang Yueran likes to describe the love to the extreme in the novel, accustomed to writing the absolute self-sacrifice, even self-destructive, self-destructive love model. The “oathbird” follows the pattern of Zhang Yueran’s love narrative, except that love has undergone a shift, mutation, obsession with love and a mad shift to attachment to love or love. The transfer of love led to the absurdity of love and love, resulting in emotional deportation and deviation. Asexual love, incestuous love, same-sex love are the lack of breeding ground for love, the lack of reasonable existence, determines the love of futility and nothing, destined to a tragic fate.
