Scam. Targeting Chinese speaking phone owner.
I neither speak Chinese Mandarin nor having any Chinese speaking friend. They sent text in Chinese and I had to translate to understand the message on my iPhone. And I am not a gardener or landscaper.
“ 您好，我家别墅花园需要重新设计绿化，朋友推荐您，请问您什么时间有空上门看看呢？”
Translated version “ Hello, the garden of my villa needs to be redesigned and greened. My friend recommended it to you. When are you free to visit us?”
