Why can't shoes, cups and scarves be given away casually?

................, this is just an auspicious saying among the people-quilt is homophonic with tragedy! Shoes are homophonic with evil and so on. ..

..... Secondly, it is possible that these things have been used, and, um (who knows how many times the buyer has tried it? ! ) ...... Many people don't like second-hand personal belongings!

.. so it is more reliable to send disposable food; Or very large durable consumer goods (such as electric fans)
