5.How to avoid translator to take commission

Many foreign merchant, they hate Chinese guide .because Chinese guide always love to take hidden commission . Especially in some Sourcing agent .they always order their staff to make commission covertly ,Everytime some translator  bring you to visit supplier, They have already asked suppliers 5%-10% hidden commission for their own in advance ,So You will never get the good price with them
How to avoid this?
When you go to somewhere first time ,you need guide .As you don’t how to go there.
So the first time you go to market with one guide .you don’t place any order. You say you just come here to check the market and .check the price .then next day you go to market on your own. to bargain the price with supplier directly. Most market supplier know English.
