Without Lao Fengxiang? It's impossible. Our business does not have this problem. You can ask for another one at the counter. Besides, Lao Fengxiang's certificate appraisal is in his own factory. There will be the words Lao Fengxiang on the certificate. I suggest you go to them. There is also Lao Fengxiang's diamond ring, which is usually engraved with "Lao Fengxiang Z". I hope these can help you.
