Why are these sentences not correct?

[Tedwonny]

I was reading a newspaper article the other day and I came across these 4 sentences - claimed to be 'Chinglish-style'.

1) Our shops should be on sale.
Should it be - the items not the shops?

2) our price is cheap.
I learnt that price collocates with low/high but I remember a native speaker of English said price can also collocate with expensive / cheap?

3) The problem was improved.
I think this is okay.

4) Because of this reason, I would like to propose a chance in our pricing scheme.
Acgain, I think this is okay at time. For conciseness, perhaps 'for this reason'.

What do you all think?

THANKS

A[STRIKE]c[/STRIKE]gain, I think this is okay [STRIKE]at time[/STRIKE]. For conciseness, perhaps 'for this reason'. You'll hear 'because of this reason', but it's poor style. Say: 'Because of this' or 'For this reason'.
