How many hospitals in Nantong can do four-dimensional color Doppler ultrasound?

I went to Beibei Palace and had a four-dimensional color Doppler ultrasound. They also allowed my family to go in and watch the baby together, and they cut it into a video as a souvenir of the baby's fetus. Now, there is a 30% discount on ordering 880 fetal four-dimensional color Doppler ultrasound set, and the current price is 6 16 yuan. Send it to 270 yuan children's photography set. Or book a 880 yuan fetal photo suit without discount, and give a pregnancy flavor suit worth 799 yuan.
