What is pet door-to-door service? What's the role?

Every Q pet baby has his own home. You can invite your best friend's pet to your baby's house, or you can visit other pet babies' houses. Pets in the same family can chat and interact with each other. Most families can produce food or daily necessities for their owners. Some families can provide special living conditions for pets entering their homes. How to enter the baby's home? You can choose different ways to enter your home, visit your friends and invite your friends, just by clicking on "Baby Home" in the right-click menu. Select "Enter Home" to open your Q pet baby's current home. If you choose "visit friends", you can choose a friend of your pet to visit his home. Select "Invite Friends" to select one of all online pet friends and invite him to visit your precious home. If you choose to "step on it casually", you will randomly enter a Q pet baby's home. Every time you go online, your pet will enter your home by default, and every time you go offline, your pet will leave home. How to use home to produce goods? In your baby's home, click the "Produce Items" button in the upper right corner of the home interface to use the function of producing items at home. Each family can only produce one product every day. The goods produced may be food or daily necessities. Different families and houses can produce different kinds of goods. The more expensive the house, the more high-grade goods it produces. A "simple hut" cannot produce anything. How to hold a party at your home? In your baby's home, click the "Hold Party" button in the upper right corner of the Home interface to open the party list, select the party you want to hold, and press OK to hold the party. To hold a party, your baby needs at least one guest at home. You can use the "invite" function of your home to invite your pet friends to your home. Different political parties have different ceilings. When the number of guests in your home exceeds the upper limit, you can't hold this party, so you can only choose to hold a bigger party. The cost of the party is paid by the host, but both the host and the guests will get the same attribute bonus through the party. The cost of a party is calculated per capita, that is, the more guests invited to the same party, the more it costs. How to use home state? Every family has a certain number of family states to use, such as "rest", "wandering" and "playing". Click the status button in the upper right corner of the homepage to enter the corresponding homepage status. Each family status lasts for 30 minutes, and if you leave home during this period, your family status will be interrupted. Every time the home state ends, there will be some special events that will make you get unexpected gains. You can not only use your own baby's family style, but also visit other baby's families to use other people's family styles. The same family can only use the status once a day, and the status of up to six different families can be used every day. How to change homes? Click the "Change Home" button on the top button bar in your own baby's home or click the "Mall" button on the top button bar in someone else's home. You can buy your favorite house in the "Buy House" tab, or you can choose your own house in the "Replace House" tab to replace it with your current house. You can give your home to your friends through the "Gift" function. There is a time limit for buying a house. When the house expires, it will disappear from your house ownership list. No, rest is also a state. Only when you step on other people's feet and do your own thing can you open the treasure chest once a day. As for how many people have it, the press is random. Answer 3 questions correctly and you can open the treasure chest, only once a day.
