Hi Jack,
Your note below:
wǒ zài xié xiào. wǒ zài zhèr zhèiyàng wǒ néng xié. wǒ xǐ wǒ de shǒu zài xǐ shǒu jiān něr zài nàr.
You've made 2 wrongs in Pinyin.
xié --> xué
něr --> nǎr
But, the gramma of the sentence is wrong. You should say:
I am at school. wǒ zài xué xiào.
I am here so I can learn. wǒ zài zhèr zhèiyàng(suǒyǐ) wǒ néng(kéyǐ) xué xí.
I wash my hands in the restroom which is there. wǒ zài nàr dē xǐ shǒu jiān xǐ shǒu.
and your question : does xin ci mean 'so'?
Not "xin ci", but "yin cǐ". suǒyǐ, yincǐ, zhèyàng mean "so". I usually use "suǒyǐ".
hope it helps ^^
The pinyin for 学校 (school) is xue2xiao4 not xie2,
A short note to help my vocab.
I am at school. I am here so I can learn(why? I don't understand what’s the meaning of this sentence ). I wash my hands in the restroom which is there.
wǒ zài xié xiào. (The first one is right!)///wǒ zài zhèr zhèiyàng xīn cǐ wǒ kě yǐ xié xí. ///wǒ xǐ wǒ de shǒu zài xǐ shǒu jiān něr zài nàr de xǐ shǒu jīan lǐ xǐ shǒu.
Hope that will help u,dude ^^!
