  ["Is Chinese metaphysics just superstition?", "Treating it as absolute prophecy is superstition. Treating it as an ancient language for observing the relationship between yourself and time makes it a cultural and psychological tool. Every reading here lands on actionable reflection — never a verdict."],
  ["Does the zodiac follow the Lunar New Year or the Start of Spring?", "Common usage follows the first day of the Lunar New Year; classical astrology follows lìchūn (Start of Spring). This app uses the classical convention, so people born in January or February may see a different zodiac than their official ID — that is expected."],
  ["What is true solar time, and why do I need to enter my birth city?", "Ancients used sundials: noon meant the sun directly overhead. Clock time is standardized by time zone, but local solar time shifts 4 minutes for every degree of longitude from the zone's centre. Your birth city corrects for this, making the hour calculation more precise."],
  ["I was born in the Southern Hemisphere — how is my chart handled?", "The 'month pillar' in a birth chart is really about season. July in the Southern Hemisphere is winter. For Southern Hemisphere births, this app adjusts the month pillar to reflect the actual season — a common and reasonable approach among practitioners."],
  ["What is a luck cycle (dàyùn) and why does it last ten years?", "Luck cycles project your chart forward through the seasonal markers (solar terms), marking roughly ten-year climate periods in your life. They are not verdicts — think of them as weather forecasts: knowing the rainy season is coming so you can pack an umbrella."],
  ["My hexagram shows something inauspicious. What do I do?", "In the Yi Jing, auspicious/inauspicious means 'this path flows / this path meets resistance' — not a sentence. When resistance appears, the classical answer is always: adjust direction, build strength, wait for timing. This app translates that into a small action you can take today."],
  ["If I cast again tomorrow, I'll get a different hexagram — which one counts?", "Tradition says 'cast once per question, sincerely, on first impulse.' The value isn't in predicting an outcome — it's in the moment you force a vague anxiety into a specific, concrete question. That act of articulation is itself already problem-solving."],
  ["Star omens like 'Seven Killings' or 'Peach Blossom' sound alarming / mystical?", "They are poetic labels ancient observers gave to common life patterns: Seven Killings points to external pressure; Peach Blossom to social magnetism; Travelling Horse to change and mobility. This app translates all of them into psychological descriptions — no fear, no mystification."],

  ["命理是迷信吗？", "把命理当作「绝对预言」是迷信；把它当作一套观察自己与时间关系的古老语言，则是文化与心理工具。本盘所有解读都落回可行动的建议，从不替您下判决。"],
  ["生肖按农历新年算，还是按立春算？", "民间常按农历正月初一，命理传统按立春换年。本盘排盘采用农历年界的传统算法，所以一二月份出生者的生肖可能与身份证习惯不同，这是正常的。"],
  ["什么是真太阳时？为什么要填出生城市？", "古人以日晷定时，太阳到头顶正上方才是「正午」。钟表时间是按时区统一的，与当地太阳时间每偏离时区中央经线 1° 就差 4 分钟。出生城市就是用来做这个校正，让时辰更准。"],
  ["南半球出生，八字怎么算？", "八字里的「月令」本质是季节。南半球的七月是冬天，所以本盘对南半球出生者按季节对冲调整月柱（业内常见的折中处理之一）, 让排盘贴合真实的季节体感。"],
  ["大运是什么？为什么十年一换？", "大运是从出生那一刻起，顺着节气往前（或往后） 推出来的「人生季节表」, 每十年一个气候段。它不是吉凶判决，更像天气预报：知道雨季要来，就备好伞。"],
  ["卦上出现「凶」字怎么办？", "《易经》里的吉凶是「此路顺/此路阻」的路况提示，不是命运宣判。遇到阻，经文给的答案从来都是：调整方向、积蓄力量、等待时机。本盘会把这些转译成今天就能做的一小步。"],
  ["摇出的卦，换个时间再摇会不一样，哪个算数？", "传统讲「不动不占，一事一占」: 同一件事以第一次诚心起的卦为准。卦的价值不在预测对错，而在它逼你把模糊的焦虑说成一个具体的问题——这件事本身就已经在解决问题了。"],
  ["神煞（如七杀、桃花） 听起来很吓人/很玄？", "它们是古人给「人生常见情境」起的代号：七杀指外部压力，桃花指人缘吸引力，驿马指变动。本盘一律把它们翻译成心理状态描述，不恐吓、不渲染。"],
