Notes
1. "表里不一”、“道貌岸然”、“满嘴仁义道德，一肚子男盗女娼" in the original. Respectively lit. "different inside and out", "dignified appearance", "virtue on the mouth, male thief and female prostitute in the belly".
2. The original exchange goes like: "A-Xu, are you going to eat vinegar?" "I'm going to eat you". "Eating vinegar" means being jealous. Jealousy is acidic for Chinese people.
3. 梁九霄 lit. "roofbeam nine firmament". Romantic sounding name. Is mentioned as Qin Jiuxiao in the first episode of the show.
4. 狗皮膏药 or "dogskin plaster" in the original. A type of medicine in TCM prescribed by quacks. Means a sham medicine that's sticky on top of being useless.
