The visiting time should not be too long(bai fang shi jian bu yi guo zhang )

The time of visiting should not be too long. If the other party is in high spirits, you may as well talk for a while; if the other party's reaction is cold and absent-minded, or if the host and his family spend time gossiping with each other and do not speculate with you, then you must immediately end the conversation and be ready to leave. In this case, even if the host asks you to stay, you should leave. At this time, the retention is often out of politeness, not sincerity. If you find the host secretly looking at the watch, you should leave with interest, because the host has already given the "eviction order".
