请保重 ; 走吧 character break-down (Pictogram Palace: Free Supplement)

请保重
Chinese characters are fundamentally built out from pictures. So for example bao3 保 indeed IS a picture of a guard!(人person口mouth木tree) Qing 请 is a pictophonetic compound character. On the left is the yanzipang which means to say or speak: in simplified yan is a mouth with sound waves 言. In modern it is the english letter i! because I the worker (工人) want to say something, something revolutionary. The phonetic element 青 is on the right that is a compound character. on top right is zhu 主 which is a column with a torch on it symbolizing the lordly manor. beneath that is the moon character yue 月 which here is symbol of that which is changeable (moon goes through phases). Qing itself is the shifting shade of blue-green which may be seen in the sea water or in the flame of a candle (see also zhu above). So qing is the idea of a color, then changeability, and thus by metaphore emotion (情). This Qing 请 exactly means the same as German “bitte”, I bid thee,

So “I bid thee guard”
guard what? Heavily!
Zhong 重 is a tougher one. On the bottom is tu3 土 the dirt character it means a clump of earth (in jia gu wen it is the clay wall of a primitive cave-house). Above tu3 is tian 田 the farmer field / rice paddy character. Tu3+Tian in that combination means 里 li, the hometown, the home village, your neighborhood, which is obviously something important.
But above 里 are 2 additional lines! What could they mean? qian 千 1000. It is the number 1000. I guess 1000 home-villages 1000 farmers houses and fields would be mighty important!

Chinese characters are combinations of pictures, symbols, some of which may also be phonetic clues as to pronunciation.

So: literally 请保重 means “I bid thee guard thy neighbor hood and they neighbors’ hoods”!

走吧
ba 巴 is a picture of a coBrA snake. It symbolizes the idea of alterity, the other. Here it is used as a phonetic element 吧 means ok.
zou 走 is a clump of earth tu3 土 on top of 正 zheng which means upright just or tu3 土 on top of 止 zhi which means stop. zhi 止 is a picture of a foot though i found it easier to think of it as a person on the left forced to stop by a tall high tree or wall on the right 上 shang means tall.
foot+dirt = go rhymes with zou
foot but no dirt means stop because you can’t walk without something to walk on, i guess.
hanzi are pictures and symbols which in turn are used as phonetic clues for more complex compound characters which are comprised of highly stylized pictures with abstract symbols and sound clues.
