Health observation outside Italian beehives

What is your bee colony like? How many spleens? Because it's just my hobby, not for production, the situation should be no problem. If it is determined to be a Chinese bee, it is not a mite; Dead bees and pupae were removed. If the amount is not large, it is normal and there is no problem. Can the spleen circle have a large number of white-headed pupae? If it is, it's broken.
