Geng Metal
First of all, would like to thanks Lilian & Lugrey for their contributions :)
Do agree with Lilian that raw metal needs to be forged in order to become sharp and useful sword/axe. Hence, she thought that Geng Metal people is tough,but through hardship/endurance they emerge as solid character with sense of responsibility.
Personally, I like below description made by Lilian as well : -
A sword never stops mid point when they are meant to cut, they cut. So Geng people will chop their ways through their goals to get what they want. Their attitude is "do-or-die". (NOTE : This is especially so when the Geng is strong)
I do agree with Lugrey that Geng person is not so much about giving into emotions (feeling bad/ pity).
To me, Sword (ie Geng Metal) is a symbol of toughness and hardiness.
On the positive notes, we can conclude that he/she is direct, determined and never admits defeat. They do not believe in wasting time on worries and will rather take action. They charge ahead without hesitation.
What are the probable shortcoming you can think of?
