My manager at Hutchin School was this Chinese flake named Simon.

Please clarify what a Chinese flake is.

I had to change from L to a Z (working)visa before I could work at hutchin School. Total visa expense was 7000MB and Simon told me before I came to Hutchin that the school would reimburse me for all expenses. I looked at my final pay sheet and it was missing the 7000rmb they owed me. I called Simon and he said he never promised me that money, another lie.

The only promises that carry any weight in China are ones that are countersigned and bear the appropriately worded red-ink stamp. As you have unfortunately discovered, oral promises can't be relied upon, and can lose you money!
Thanks for spilling the beans online to forewarn any of us who might have applied to that school.
Hutchin School of Shijiazhuang definitely comes across as one to be avoided at all costs.
