Most of our business are locally based. Since our custmers are the end-users, the size of the order usually is not too large. The orders are mostly on replacement parts, and for those who have engineers working in the companies, they often only order small amount of parts since the engineers know exactly which parts of the machine are damaged. Otherwise they would order a whole section of the machinery, just like a full kit. For example, when there's a hole in a shirt, if you know how to mend it, you would only buy a small piece of fabric. If you don't, then you might need to buy a whole sleeve or even the entire shirt.

What we did mainly is local business, because I place customer user, so order quantity department well, can heavy already.
Order is usually that some parts replace, depends on the customer has engineers, will know the bad baa when having the engineer, it is only order a small amount of part
Otherwise Know it buy full kit fruit already one part not whole in the machines in the departments
For example namely it is pieces of shirt that wear Left deviation a gallery, unless it know not mending buy by pieces of cloth already, well, know not if mending, buy not tucking inside the sleeve onlying,even become by pieces of shirt

We mainly do are the local business, because my customer is with the family, therefore the order already quantity is cannot be big Order usually is the partial part replace, regards the customer to have no engineer, has engineer to be able to know badly baa, therefore only is the order few components otherwise it can full kit and buy fruit department machine already some entire part for example, namely the unlined upper garment puts on the left hole, the knowledge makes up already buys the block cloth, does not know makes up buys Cheng Chihhsiu, even Cheng Chienshan

Because of some uncertain parts in the text, as I tried to understand as much as I could, the translation may unaviodably go a bit far from the original text.

Translation:
Given that we do business in the local region (HK?)/ do local business, our clients who are users themselves or clients accompanied with a technician (工程師是什麼？), who are supposed to know which parts do not work, do not order for a large amount of components of a machine, usually for the sake of renewing a part.
Or they may purchase a full kit of the particular section of the machine.
For instance, when a hole has been left on a garment, buy a piece of cloth to mend it if one knows how to or buy the sleeve or even a complete one if one do not.

We mainly conduct localised business, we only get small quantity orders because the buyers are end-user. The orders are usually parts of machines for replacement, depends whether the buyers have their own engineers or not, they will know which part is out of order and, therefore they will only order a small amount of parts.
Or else they will buy a complete section of the machines.
