There is a plus sign in the upper left corner of the screen. Click on it to open the menu. On the right side of the menu is the "Family" column. The first one is your daughter-in-law, and the last two are your children. Did you find a wife? There is a heart-shaped icon on the map. Run to take your daughter-in-law home, feed her meat, shout and rub, and then click on the bottom two character columns in the family column, and you will find two eggs at home. Then leave it alone. You go out and kill the prey to upgrade, bring the meat back to feed her daughter-in-law, and the eggs will have experience and finally hatch. I cann't believe I didn't give gold coins
