Please tell some big communities in Xi 'an (residents 1000 or above).

Daniu Community, Yanming Community in the southern suburbs, Qinglong Community near the South Second Ring Road, etc. If you pass the doorman, you should boldly enlarge yourself. You can pretend to call and say "I'll be right there", but how many floors should you pay attention to? What is the number? The doorman was afraid to ask. If he asks, he can answer or lie about repairing the computer. When you enter a customer's home, you should respect people and be generous. Stand at the door one meter from the cat's eye, clearly state your purpose, sweet talk, and call more uncles and aunts, which makes people look pleasing to the eye, unlike thieves or liars. Good luck.
