中国人一直以来都被认为在行事和观念上相对保守和含蓄，这与古代遗传下来的习俗风气密不可分。一个明显的例子是性教育，至今在中国的家庭中，这仍然是一个难以启齿的话题。父母很少与孩子进行关于性教育的交流，尽管一些生理知识可以在课堂上学到，并且互联网的普及也减轻了这种尴尬。那么，古人又是如何进行性教育的呢？他们是否有性教育的风俗呢？答案是肯定的。

在古代，有一种叫做“嫁妆画”的性教育方式。这些“嫁妆画”实际上是一卷卷印有房事图画的“春宫图”。由于社会的需求，古人多使用木版印刷这些画，它们充满了乡土气息和民间色彩。在女儿出嫁前，父母通常会购买一两卷“嫁妆画”，将其放在嫁妆中，随女儿一起带到新家。在新婚之夜，缺乏性知识的新婚夫妇通常会将这些画铺在床上，用它们作为性教育读本。因此，“嫁妆画”可以被看作是古代嫁女儿时必备的陪嫁品，它在民间还有一个称呼叫做“压箱底”。古人看待这些画的感觉，有点像现代夫妻之间观看成人影片的感觉。

从唐代到宋代，有很多人画过“春宫图”，其中还有一些著名的画家专门画这种图。甚至有些“春宫图”从侧面反映了一些历史风俗和事件。到了明朝时期，“春宫图”的发展达到了顶峰。
可以看出，古代中国人也有一种形式的性教育，尽管内容相对单一且缺乏系统性。然而，这种教育方式在当时的社会中被广泛接受和使用。而今天，虽然中国人在性教育方面仍然相对保守，但随着社会的进步和观念的改变，性教育的重要性也逐渐被人们所认识和重视。


----------Introduction in English----------
Chinese people have always been considered relatively conservative and reserved in their actions and concepts, which is closely related to the customs and traditions inherited from ancient times. A clear example is sex education, which is still a difficult topic to discuss in Chinese families today. Parents rarely communicate with their children about sex education, although some physiological knowledge can be learned in the classroom, and the popularity of the internet has also alleviated this embarrassment. So, how did the ancients conduct sex education? Do they have a custom of sexual education? The answer is yes.
In ancient times, there was a method of sex education called "dowry painting". These "dowry paintings" are actually rolls of "spring palace paintings" printed with pictures of sexual intercourse. Due to the needs of society, ancient people used woodblock printing to print these paintings, which were full of local flavor and folk colors. Before their daughter gets married, parents usually purchase one or two rolls of "dowry paintings" and place them in the dowry, taking them with their daughter to their new home. On their wedding night, newlyweds who lack sexual knowledge usually lay these paintings on the bed and use them as sex education textbooks. Therefore, "dowry painting" can be seen as a necessary accessory for marrying daughters in ancient times, and it is also known as "pressing the bottom of the box" in folk. The way ancient people viewed these paintings was a bit like watching adult films between modern couples.
From the Tang Dynasty to the Song Dynasty, many people have painted the "Spring Palace Painting", among which some famous painters specialize in painting this kind of painting. Even some "Spring Palace Pictures" indirectly reflect some historical customs and events. During the Ming Dynasty, the development of the "Spring Palace Map" reached its peak.
It can be seen that ancient Chinese people also had a form of sex education, although the content was relatively single and lacked systematicity. However, this educational method was widely accepted and used in society at that time. Today, although Chinese people are still relatively conservative in sex education, with the progress of society and changes in attitudes, the importance of sex education has gradually been recognized and valued by people.
