Today I had an argument with a petty thief. Since the thief is a woman and was born on March 8th, I called her a "March 8th (san ba) petty thief". She then called me a "tortoise (wang ba)". Since I was born, I've known that "March 8th" refers to women and "tortoise" refers to men, but I didn't know why. Today, after reading her response, I suddenly understood why. Look carefully at the difference between "tortoise" and "March 8th". It turns out that in the character for "tortoise", there is an extra "|". Haha! Now everyone knows why "March 8th" refers to women and "tortoise" refers to men! I wonder what the person who invented these characters would think if they knew... The depth and complexity of Chinese characters are truly amazing, haha.
