3. Cov Lus Cim Tseem Ceeb

· Cov ntawv xaiv: Cov ntaub ntawv nqus (xws li, ntawv nplej, ntawv lim) ua haujlwm zoo tshaj plaws. Cov ntawv coated yuav tsis coj cov xim zoo.

· Xim Tswj: Kho qhov tob los ntawm kev hloov xim xim, lub sij hawm immersion, lossis rov ua cov txheej txheem.

· Kev nyab xeeb: Hnav hnab looj tes thiab daim npog qhov ncauj kom tsis txhob sib chwv ntawm daim tawv nqaij los yog nqus cov xim xim.

· Kev pov tseg pov tseg: Cov dej khib nyiab yuav tsum tau muab khaws cia thiab kho kom zoo -tsis txhob nchuav nws ncaj qha rau hauv qhov dej.

4. Cov ntawv thov

· Kev laus cuam tshuam rau calligraphy lossis painting ntawv
