1. Never sleep on overpasses, streets, internet cafes, or in parks.

2. If you need to stay overnight, go to the airport terminal; not only is there a place to sleep, but they also provide hot water, phone charging, and even Wi-Fi.

3. When you wake up, head straight to McDonald's, find a coffee cup that someone else has left behind, and then go to the counter for unlimited refills.

4. At noon, find a nearby hotel; many rooms leave their doors open after guests check out, and you can find an empty room to take a hot shower.

5. In the afternoon, you can go to Haidilao for free snacks, and in the evening, head to Hema supermarket for unlimited tastings. When the staff throws away unsold bread, you can take some to go.

6. If you're hungry, go to KFC to eat leftover burgers, fries, Coke, and chicken nuggets.

7. If you need to change clothes, go to the fitting room in a large mall, find some clothes that customers tried on but didn't buy, and quietly change into them, stuffing your old clothes into a corner. Remember to choose less conspicuous styles.

8. If the airport is too far at night, go to a 24-hour convenience store, pretend to browse for items, and find a corner to sit and rest. The staff usually won't kick you out, and you can grab some expired free snacks.

9. If you want to do laundry, go to a self-service laundromat, pretend to be there to pick up clothes, and while no one is watching, use the washing machine and dryer that someone just finished using to clean your clothes.

10. If you need a haircut, you can wait at the entrance of a barbershop. When you see someone finishing their haircut, go in and tell the barber, "Just give me a little trim," and often they will help you with a simple trim for free.

10. In the spring and summer, when there are many mosquitoes, you can go to the pharmacy and look for trial-sized mosquito repellent or floral water; take a bit and apply it to yourself to prevent bites, and you can also rest a bit under the pharmacy's awning.

11. If your phone has no balance, make sure to use Wi-Fi to access Telegram and Twitter, and don't forget to recharge your Dogecoin.
