It's entirely possible. This has nothing to do with feng shui. What matters is their local customs. If there is no relevant custom in the place where the landlord is located, then don't care. Feng Shui is mainly about learning to thrive. There are not so many halls, and everything is not necessarily attributed to Feng Shui.
In fact, even if there is a custom, I don't think it matters. On the contrary, it is very sweet to wrap jiaozi for yourself. Moreover, glutinous rice can relieve people's nervousness and be more hungry, which is quite good.
I wish the landlord's children good results in the exam.
