My friend and I went to the south of Nanning by car, near Qingshan food market. Many people say it's good. I didn't know how many weeks you were pregnant. It is generally better to do it in 22-24 weeks. Four-dimensional color Doppler ultrasound can image the body surface, and fetal congenital malformations such as cleft lip and palate, limb dysplasia, meningocele, spina bifida and gastroschisis can be found more clearly. It should be checked. I wish pregnant mothers good pregnancy!
