chinese tradition

typical Chinese had super duper complicated religion with tons of rules!!!
went back to my weird old hometown with my mom + my aunt + her husband to do some Chinese tradition thingy which i kinda still having hard time to understand as my hokkien ain't good enough to understand what my grandma trying to say and my mom + my aunt ain't good in explaining.

this is what i understand so far.
i had 2 sets of parents?
i own 2 surname now?
Yap Ng Tit Kian?
葉黃 特健??
why??
according to a fortune teller, by doing so i can gain more happiness?
why??
this is the part where i'm lost. no idea what my mom and aunt trying to say.

so, i kinda ignore it.
+ look at the bright side, i manage to get some stuff in the end though.

+ a nice ribbon on my wrist.
+ angpao from my aunt.

yay!!!??

p.s.
banting bat gut teh(chinese herbal pork) ain't good.
I'm okie with the taste but the pork is just too fat!!! the fat is around 1.5 inches and there's hardly an inch of meat there!! I'm too shy to snap a picture with my phone in front of my grandma. sorry bout that but you can try to imagine it yourself. it is pretty easy to imagine.
still wondering how can a pig become that fat??
guess those pigs didn't even manage to walk? and what they did were sleep, eat and waiting to be kill?
XD
