忙活 (máng huo): Pour être vraiment occupé

In order to prepare for her son's wedding, Mom busied herself in the kitchen all day and didn't even have time to take a sip of water.

After retiring, Grandpa busies himself in the yard every day planting vegetables and watering flowers, and his days feel especially fulfilling.

On moving day, a few of us friends helped him busily from morning till night, and we were so tired we could hardly stand up straight.

Before the Spring Festival, every household is busy with thorough cleaning and putting up spring couplets, creating a festive scene everywhere.
