In the pursuit of perfection, Kuan normally spends 30 to 40 hours on an egg before he considers the work finished. If at the last minute a small crack appears, to avoid letting anyone see it as well as to avoid planting the seeds of regret, he immediately throws that egg away.
而為了追求完美，往往花費三、四十小時，眼見作品即將完成，卻在最後時刻出現破綻，儘管旁人看不出破綻所在，他也不讓自己有後悔的時間，馬上把蛋給毀了。
