Kitajci so spol prihajajočega otroka izračunavali tudi preko materine starosti in meseca zanositve. Ta tabela, ki so jo našli pred približno 700 leti v kraljevi grobnici blizu Pekinga, je še danes 93% zanesljiva. Pripravljeni? Izračunajte materino starost na dan spočetja otroka in ugotovite ali bo deček ali deklica. Na primer, 30 letna ženska, ki je zanosila v 1. mesecu lunarnega leta bo glede na izračun dala rojstvo dečku.
D = deklica
F = fantek
