No, I don't think you will know Chinese if you know kanji! some kanji are different from Chinese's and kanji mostly consist traditional Chinese words... it's quite different from simplified Chinese words......
Agree, because Chinese character and kanjiツ…
1. they have same wording but different meanings- Chinese(japanses)
窶「テ冷?ケツュツ to be forced to do something (窶「テ冷?ケツュ to study)
ナセテサ窶慊「 to review a incident (ナ椎ク窶慊「 to discuss)
窶卍才? to pay attention to sth or sbd ONLY (窶卍才? warning or to pay attention to sth or sbd)
ナ停?凪?ーテ speak loudy and disturb other people (ナ停?凪?ーテ to fight)
2. some Chinese character have a similar structure to kanj
ツ戰テゥツヲ/(ツ静ュ窶慊ャ)
3. some of them are the same wording but in revered sequence:
in Chinese ナスm窶「ツコ ヒ彗窶「ツス
in Japanese 窶「ツコナスm 窶「ツスヒ彗
4. some kanji are made by Japanese, Chinese do not have them originally, they cannot be found in a Chinese dictionary. (may be modified form Chinese characters)
ツ渋窶價 -- ツ渋 (涉)???
窶板ウ (窶板エ)
ツ静ュ窶慊ャ (ツ戰テゥツヲ)
5. many kanji is meaningless in Chinese: (if kanji is translate to Chinese...)
窶堋ィ窶「窶藩廚窶堙俄?愿シ窶堙ゥ(ツ静エテ?U) ツ静倪?「窶?窶「[) ツ静披?堋ソ窶堙。窶堙ア(窶ーd邃「Z)
窶伉イ窶ケテ?スツョ(窶「L窶ケテ??弋テ「X) 窶禿ゥ窶督セ窶堋ッ(テェt窶督セ/窶愿コツ出) 窶敕イツ行窶ケ@ (窶敕イ窶ケ@) 窶「テ吮?懌??窶敕妥。')
6. Some kanji is imported from ancient Chinese, now they are not used in Chinese
窶懌? in ancient Chinese meaning: hot water, now it become soup.
窶懌? in japnese meaning: hot water
I come from Hong Kong, just know a little Japanese and English. If there are any mistakes, please correct them.
Nevertheless, there are many Chinese character and Japanese kanji have same meaning and similar pronunciation. So that It help you to learn Japanese if you learnt Chinese (I prefer Traditional Chinese), and vice versa.
