Secondly, if your family really wants a boy or a girl, you can choose three generations of test tubes. But this is not allowed in China. You can choose a foreign hospital. Personally, I strongly recommend going to Moscow, Russia to do BFG. This is the first health center in Europe dedicated to Chinese people, which adopts IVF, ICSI, PGD, PGS, genetic eugenics, non-invasive prenatal diagnosis (NIPT), high-throughput sequencing (NGS), gene chip detection (SNP) and other technologies.
