Beijing gaode behind GRC has been punished many times, which can be said to be incorrigible. In our circle, it stinks and stinks. Everyone hopes that the certificate will be cheaper, which can lower the testing standard and even open the certificate at will, which will disrupt the market order and make our practitioners suffer unwarranted accusations. I might as well choose some reliable international gem laboratories and buy one with peace of mind. There is no good road to plagiarism, it will only narrow the road.
