RE: In china the number 7 is very lucky!2 Mar 2022 12:48
From Google:
The number 7 (?, pinyin: qi) in Mandarin sounds like "even" in Mandarin (?, pinyin: qí), so it is a good number for relationships. ... Seven can also be considered an unlucky number since the 7th month (July) is a "ghost month". It also sounds like "to deceive" (?, pinyin: qi) in Mandarin.
