Sometime hope arise when everyone think there is no hope...

But JCY mainly supply mechanical parts if I am not mistaken, the quantity of parts supplied is fixed but precision level might need to be increase with time, price of parts supply should decrease with each cost reduction effort, meaning to say increase of storage/ price shouldn't impact JCY too much, but decrease of sales quantity will. IMHO, the main factors for JCY are:
1. cost of material e.g. steel etc;
2. labor cost;
3. energy cost
4. favorable exchange rate and most importantly
5. demand.
