How do you think about chinese made?

Many kind of commodities are made in China , and I met many foreign friends use the phones ,computeres ,books ,even socks and so on ..are all made in china. Sometimes ,when we were free chatting ,I often ask that how do you think about the goods quality from China. they out of courtesy ,are all same response: its cheap ,the qulaity is just so so .......
I understand that they wanted to make me sad .
As a quality control person ,I want to know the truth and the objective comments ,would you help me?

"sing " "hich are all made in china "or you can just write  " made in china"

here you write sometimes , so your grammer is not right
