Lan Yan is a biological species, and its main body is passeriformes. It is distributed in south-central Africa, including the southern Arabian Peninsula and the whole African continent south of the Sahara Desert (Tropic of Cancer). There are also many people who keep Lan Yan birds as pets at home and often bathe them. In fact, birds bathe themselves. Just provide a bath tray and put it in a cage. But if you want to help it wash, you can buy a watering can for watering flowers, spray it into the sky when the sun is shining, and let it fall freely on the bird. Of course, if you want the birds not to be cold in winter, you'd better turn on a heater indoors and then prepare a towel to wipe them.
