Four pieces of lore in one tap: the western zodiac sign (12 signs by birth month/day), the Chinese zodiac animal (12 animals cycled by lunar year), the five-element year (Wood, Fire, Earth, Metal, Water — each ruling two consecutive years), and the birthstone by birth month. Because the Chinese New Year shifts between January 21 and February 20, babies born in late January or February should double-check which side of the lunar boundary they fall on.
一次查询得到四样传统知识：西方星座（按公历生日划分 12 星座）、中国生肖（12 生肖按农历年循环）、五行年份（木、火、土、金、水，每五行掌管连续两年）、以及按出生月份的诞生石。由于农历新年在 1 月 21 日–2 月 20 日之间浮动，一月末或二月出生的宝宝应确认自己落在农历分界线的哪一侧。
