加强(jiā qiáng): to reinforce

Watch how each character of 加强 is written, one at a time. When a character is finished, the next one draws.

How 加强 is used in everyday Chinese — the speaker reads the whole sentence.

• 勇气是非常重要的。比如肌肉，经常使用才得以加强。

  yǒng qì shì fēi cháng zhòng yào de bǐ rú jī ròu jīng cháng shǐ yòng cái dé yǐ jiā qiáng

  Courage is very important. Like a muscle, it is strengthened by use.

• 要做到这一点，就要加强师资培训工作。

  yào zuò dào zhè yī diǎn jiù yào jiā qiáng shī zī péi xùn gōng zuò

  To enable them to do so, teacher training must be intensified.
